DIRNAME is the compilation directory of a particular source file.
Only some debug formats provide this info.
FULLNAME can be the last known absolute path to the file in question.
Space for the path must have been malloc'd. If a path substitution
is applied we free the old value and set a new one.
On Success
A valid file descriptor is returned. ( the return value is positive )
FULLNAME is set to the absolute path to the file just opened.
The caller is responsible for freeing FULLNAME.
On Failure
An invalid file descriptor is returned. ( the return value is negative )
FULLNAME is set to NULL. */
