+ FILENAME should be the filename to open.
+ 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

+ 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).
