The exported functions can be accessed as attributes, or by indexing with the function name. Examples: <obj>.qsort -> callable object <obj>['qsort'] -> callable object Calling the functions releases the Python GIL during the call and reacquires it afterwards. z<uninitialized>r NFc sb |�_ �j� |r� tO � |r$� tO � G � �fdd�dt�}|�_|d krXt�j |��_n|�_d S )Nc s e Zd Z� Z�jZdS )z CDLL.__init__.<locals>._FuncPtrN)r( r) r* r- �_func_restype_r, r" )r/ rW r" r# �_FuncPtrQ s r� )�_name� _func_flags_r4 r5 r: r� �_dlopen�_handle)rW r� �modeZhandler& r' r� r" )r/ rW r# �__init__G s z CDLL.__init__c C s8 d| j j| j| jtjd d @ t| �tjd d @ f S )Nz<%s '%s', handle %x at %#x>� r )rX r( r� r� �_sys�maxsizer� )rW r" r" r# rU [ s z CDLL.__repr__c C s6 |j d�r |jd�r t|��| j|�}t| ||� |S )N�__)� startswith�endswith�AttributeError� __getitem__�setattr)rW r� �funcr" r" r# � __getattr__a s zCDLL.__getattr__c C s" | j || f�}t|t�s ||_|S )N)r� r r r( )rW Zname_or_ordinalr� r" r" r# r� h s zCDLL.__getitem__)r( r) r* �__doc__r2 r� rd r� r� r� r� � DEFAULT_MODEr� rU r� r� r" r" r" r# r� 2 s r� c @ s e Zd ZdZeeB ZdS )�PyDLLz�This class represents the Python library itself.

From AIX 5.3 Difference Addendum (December 2004) 2.9 SVR4 linking affinity Nowadays, there are two major object file formats used by the operating systems: XCOFF: The COFF enhanced by IBM and others. The original COFF (Common Object File Format) was the base of SVR3 and BSD 4.2 systems. ELF: Executable and Linking Format that was developed by AT&T and is a base for SVR4 UNIX. While the shared library content is identical on AIX - one is located as a filepath name (svr4 style) and the other is located as a member of an archive (and the archive is located as a filepath name). The key difference arises when supporting multiple abi formats (i.e., 32 and 64 bit). For svr4 either only one ABI is supported, or there are two directories, or there are different file names. The most common solution for multiple ABI is multiple directories. For the XCOFF (aka AIX) style - one directory (one archive file) is sufficient as multiple shared libraries can be in the archive - even sharing the same name. In documentation the archive is also referred to as the "base" and the shared library object is referred to as the "member". For dlopen() on AIX (read initAndLoad()) the calls are similar. Default activity occurs when no path information is provided. When path information is provided dlopen() does not search any other directories. For SVR4 - the shared library name is the name of the file expected: libFOO.so For AIX - the shared library is expressed as base(member). The search is for the base (e.g., libFOO.a) and once the base is found the shared library - identified by member (e.g., libFOO.so, or shr.o) is located and loaded. The mode bit RTLD_MEMBER tells initAndLoad() that it needs to use the AIX (SVR3) naming style.

From AIX 5.3 Difference Addendum (December 2004) 2.9 SVR4 linking affinity Nowadays, there are two major object file formats used by the operating systems: XCOFF: The COFF enhanced by IBM and others. The original COFF (Common Object File Format) was the base of SVR3 and BSD 4.2 systems. ELF: Executable and Linking Format that was developed by AT&T and is a base for SVR4 UNIX. While the shared library content is identical on AIX - one is located as a filepath name (svr4 style) and the other is located as a member of an archive (and the archive is located as a filepath name). The key difference arises when supporting multiple abi formats (i.e., 32 and 64 bit). For svr4 either only one ABI is supported, or there are two directories, or there are different file names. The most common solution for multiple ABI is multiple directories. For the XCOFF (aka AIX) style - one directory (one archive file) is sufficient as multiple shared libraries can be in the archive - even sharing the same name. In documentation the archive is also referred to as the "base" and the shared library object is referred to as the "member". For dlopen() on AIX (read initAndLoad()) the calls are similar. Default activity occurs when no path information is provided. When path information is provided dlopen() does not search any other directories. For SVR4 - the shared library name is the name of the file expected: libFOO.so For AIX - the shared library is expressed as base(member). The search is for the base (e.g., libFOO.a) and once the base is found the shared library - identified by member (e.g., libFOO.so, or shr.o) is located and loaded. The mode bit RTLD_MEMBER tells initAndLoad() that it needs to use the AIX (SVR3) naming style. z%Michael Felt <aixtools@felt.demon.nl>� N)�environ�path)� executable)�c_void_p�sizeof)�Popen�PIPE�DEVNULL� )�maxsizec s � fdd�}t t| �|d�S )Nc sL | � � �}g }z |r*|�dt|�� �� qW n tk r@ Y nX |pJtgS )Nr )�split�insert�int�pop� ValueErrorr )Zlibname�partsZnums��sep� �#/usr/lib64/python3.8/ctypes/_aix.py� _num_version> s z#_last_version.<locals>._num_version)�key)�max�reversed)Zlibnamesr r r r r � _last_version= s r c C s: d }| j D ]*}|�d�r |}q d|kr |�d� S q d S )N)�/z./z../ZINDEX� )�stdout� startswith�rstrip)�p� ld_header�liner r r � get_ld_headerJ s r# c C s0 g }| j D ] }t�d|�r&|�|� q q,q |S )Nz[0-9])r �re�match�append)r �infor" r r r �get_ld_header_infoT s r( c C s\ g }t ddt� �d| gdttd�}t|�}|rF|�|t|�f� q"qFq"|j�� |� � |S )z� Parse the header of the loader section of executable and archives This function calls /usr/bin/dump -H as a subprocess and returns a list of (ld_header, ld_header_info) tuples. z /usr/bin/dumpz-Xz-HT)Zuniversal_newlinesr �stderr) r �AIX_ABIr r r# r& r( r �close�wait)�fileZ ldr_headersr r! r r r �get_ld_headersa s � r. c C s6 g }| D ](\}}d|kr|� ||�d�d� � q|S )z� extract the shareable objects from ld_headers character "[" is used to strip off the path information.

This scheme inserted either 64 or _64 between libFOO and .so - generally libFOO_64.so, but occasionally libFOO64.so �libz\.so\.[0-9]+[0-9.]*z_?64\.so\.[0-9]+[0-9.]*r �.N)r$ r4 r& r= r )rD rB Zexprsr7 Zversionsr" �mr r r � get_version� s � rI c C sb d| � d�}t ||�}|r |S tdkr<d| � d�}t ||�}|rD|S t| |�}|rV|S t|�S dS )ab Return an archive member matching the request in name.

If not available, also search for a file (or link) with a .so suffix. AIX supports two types of schemes that can be used with dlopen(). The so-called SystemV Release4 (svr4) format is commonly suffixed with .so while the (default) AIX scheme has the library (archive) ending with the suffix .a As an archive has multiple members (e.g., 32-bit and 64-bit) in one file the argument passed to dlopen must include both the library and the member names in a single string. find_library() looks first for an archive (.a) with a suitable member. If no archive+member pair is found, look for a .so file.

From AIX 5.3 Difference Addendum (December 2004) 2.9 SVR4 linking affinity Nowadays, there are two major object file formats used by the operating systems: XCOFF: The COFF enhanced by IBM and others. The original COFF (Common Object File Format) was the base of SVR3 and BSD 4.2 systems. ELF: Executable and Linking Format that was developed by AT&T and is a base for SVR4 UNIX. While the shared library content is identical on AIX - one is located as a filepath name (svr4 style) and the other is located as a member of an archive (and the archive is located as a filepath name). The key difference arises when supporting multiple abi formats (i.e., 32 and 64 bit). For svr4 either only one ABI is supported, or there are two directories, or there are different file names. The most common solution for multiple ABI is multiple directories. For the XCOFF (aka AIX) style - one directory (one archive file) is sufficient as multiple shared libraries can be in the archive - even sharing the same name. In documentation the archive is also referred to as the "base" and the shared library object is referred to as the "member". For dlopen() on AIX (read initAndLoad()) the calls are similar. Default activity occurs when no path information is provided. When path information is provided dlopen() does not search any other directories. For SVR4 - the shared library name is the name of the file expected: libFOO.so For AIX - the shared library is expressed as base(member). The search is for the base (e.g., libFOO.a) and once the base is found the shared library - identified by member (e.g., libFOO.so, or shr.o) is located and loaded. The mode bit RTLD_MEMBER tells initAndLoad() that it needs to use the AIX (SVR3) naming style. z%Michael Felt <aixtools@felt.demon.nl>� N)�environ�path)� executable)�c_void_p�sizeof)�Popen�PIPE�DEVNULL� )�maxsizec s � fdd�}t t| �|d�S )Nc sL | � � �}g }z |r*|�dt|�� �� qW n tk r@ Y nX |pJtgS )Nr )�split�insert�int�pop� ValueErrorr )Zlibname�partsZnums��sep� �#/usr/lib64/python3.8/ctypes/_aix.py� _num_version> s z#_last_version.<locals>._num_version)�key)�max�reversed)Zlibnamesr r r r r � _last_version= s r c C s: d }| j D ]*}|�d�r |}q d|kr |�d� S q d S )N)�/z./z../ZINDEX� )�stdout� startswith�rstrip)�p� ld_header�liner r r � get_ld_headerJ s r# c C s0 g }| j D ] }t�d|�r&|�|� q q,q |S )Nz[0-9])r �re�match�append)r �infor" r r r �get_ld_header_infoT s r( c C s\ g }t ddt� �d| gdttd�}t|�}|rF|�|t|�f� q"qFq"|j�� |� � |S )z� Parse the header of the loader section of executable and archives This function calls /usr/bin/dump -H as a subprocess and returns a list of (ld_header, ld_header_info) tuples. z /usr/bin/dumpz-Xz-HT)Zuniversal_newlinesr �stderr) r �AIX_ABIr r r# r& r( r �close�wait)�fileZ ldr_headersr r! r r r �get_ld_headersa s � r. c C s6 g }| D ](\}}d|kr|� ||�d�d� � q|S )z� extract the shareable objects from ld_headers character "[" is used to strip off the path information.

This scheme inserted either 64 or _64 between libFOO and .so - generally libFOO_64.so, but occasionally libFOO64.so �libz\.so\.[0-9]+[0-9.]*z_?64\.so\.[0-9]+[0-9.]*r �.N)r$ r4 r& r= r )rD rB Zexprsr7 Zversionsr" �mr r r � get_version� s � rI c C sb d| � d�}t ||�}|r |S tdkr<d| � d�}t ||�}|rD|S t| |�}|rV|S t|�S dS )ab Return an archive member matching the request in name.

If not available, also search for a file (or link) with a .so suffix. AIX supports two types of schemes that can be used with dlopen(). The so-called SystemV Release4 (svr4) format is commonly suffixed with .so while the (default) AIX scheme has the library (archive) ending with the suffix .a As an archive has multiple members (e.g., 32-bit and 64-bit) in one file the argument passed to dlopen must include both the library and the member names in a single string. find_library() looks first for an archive (.a) with a suitable member. If no archive+member pair is found, look for a .so file.
