Update of /cvsroot/ctypes/ctypes/docs In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv12629/docs Modified Files: reference.stx Log Message: documented loading of shared libraries Index: reference.stx =================================================================== RCS file: /cvsroot/ctypes/ctypes/docs/reference.stx,v retrieving revision 1.6 retrieving revision 1.7 diff -C2 -d -r1.6 -r1.7 *** reference.stx 31 Jul 2003 18:10:47 -0000 1.6 --- reference.stx 13 May 2005 13:45:03 -0000 1.7 *************** *** 10,13 **** --- 10,70 ---- This reference is probably not worth it's name, so incomplete it is. + Loading shared libraries + + ctypes defines some library loader objects which can load shared + libraries. Functions accessed as attributes of shared library + objects will be called with different calling conventions, + depending on the Loader which returned the library object. (FIXME: + add a section about C function objects and how to set the calling + convention) + + 'cdll' -- Loader for shared libraries using the standard C calling + convention of the OS platform (known as cdecl in Windows). + + 'windll' (Windows only) -- For libraries using the stdcall calling + conventions (all Windows system libraries). + + 'oledll' (Windows only) -- Like 'windll', additionaly assumes the + functions return a Windows 'HRESULT' error code. The error code is + used to automatically raise 'WindowsError' Python exceptions when + the function call fails. + + Methods of loader objects: + + 'LoadLibrary(libname)' -- Loads the library given by + libname. On most systems libname ist the filename of the + shared library; when it's not a path name it will be searched + in a system dependent list of locations (on many systems + additional search paths can be specified by an environment + variable). Sometimes extensions like .dll on Windows can be + omitted. + + 'LoadLibraryVersion(name, version)' -- Builds a (system + depend) filename from the library name and version and loads + it. 'name' is the library name without prefix like lib, + suffixes like .so, .dylib or version number (this form is used + for the posix linker option -l). 'version' is the major + version number (for platforms which code this into the + filename). This should be used if a library is available on + different platforms (using the particular naming convention of + each platform). + + 'find(name)' -- Tries to find a library and loads it. 'name' + is the library name (as in LoadLibraryVersion above). After + loading, the filename of the loaded library is printed on + stdout. This function might call other programs like the + compiler to find the library. When you use ctypes to write a + shared library wrapping, consider using LoadLibraryVersion + instead (or LoadLibrary, if the library is platform specific). + + Library loading is also implemented as attribute access of the + loader objects. LoadLibrary is called with the attribute name, + and the returned dll object is cached as attribute value. + Additionaly, key lookup can be used, so cdll.libname is the + same as cdll['libname']. Library names beginning with an + underscore (_) can't be accessed as attributes of a loader + object (use LoadLibrary). + + Common operations on ctypes instances |
