(C) 1996 AROS - The Amiga Replacement OS
- It invoked a Stop entry/exit handler ( Installed by StopChunk[s] or StopOnExit )
- An error occured. (return value will be negative.)
- The parser reached EOF and returns IFFERR_EOF.
IFFPARSE_STEP - The parser steps through the file, returning to the user each time it enters (returns NULL) and each time it exits (return (IFFERR_EOC) a chunk. It will also invoke entry/exit - handlers.
IFFPARSE_RAWSTEP - same as IFFPARSE_STEP except that in this mode the parse won't invoke any handlers.
Added lots of debug output
