/*
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.
