find_library() function (or ctypes.util.find_library).
Returns the first library found, which can be the library's name
or the path to the library file, depending on find_library().
Returns None if no library is found.
arguments:
* candidates -- iterable with library names
* find_library -- function that takes one positional arg (candidate)
and returns a non-empty str if a library has been found.
Any "false" value (None,False,empty str) is interpreted
as "library not found".
Defaults to ctypes.util.find_library if not given or
None.

Returns: the loaded library
arguments:
* candidates -- candidates list for locate_library()
* cygwin_lib -- name of the cygwin library
* name -- lib identifier (for logging). Defaults to None.
* win_cls -- class that is used to instantiate the library on
win32 platforms. Defaults to None (-> ctypes.CDLL).
* cygwin_cls -- library class for cygwin platforms.
Defaults to None (-> ctypes.CDLL).
* others_cls -- library class for all other platforms.
Defaults to None (-> ctypes.CDLL).
* find_library -- see locate_library(). Defaults to None.
* check_symbols -- either None or a list of symbols that the loaded lib
must provide (hasattr(<>)) in order to be considered
valid. LibraryMissingSymbolsException is raised if
any symbol is missing.
raises:
* NoLibraryCandidatesException
* LibraryNotFoundException
* LibraryNotLoadedException
* LibraryMissingSymbolsException
