/*
	Retrieve the file, line, column, and offset represented by
	the given source location, as specified in a # line directive.

	Example: given the following source code in a file somefile.c

	\code
	#123 "dummy.c" 1

	static int func(void)
	{
	return 0;
	}
	\endcode

	the location information returned by this function would be

	File: dummy.c Line: 124 Column: 12

	whereas clang_getExpansionLocation would have returned

	File: somefile.c Line: 3 Column: 12

	Parameter location the location within a source file that will be decomposed
	into its parts.

	Parameter filename [out] if non-NULL, will be set to the filename of the
	source location. Note that filenames returned will be for "virtual" files,
	which don't necessarily exist on the machine running clang - e.g. when
	parsing preprocessed output obtained from a different environment. If
	a non-NULL value is passed in, remember to dispose of the returned value
	using clang_disposeString() once you've finished with it. For an invalid
	source location, an empty string is returned.

	Parameter line [out] if non-NULL, will be set to the line number of the
	source location. For an invalid source location, zero is returned.

	Parameter column [out] if non-NULL, will be set to the column number of the
	source location. For an invalid source location, zero is returned.
