compile tested only. btw... why dont we wrap malloc to automatically include these checks? there is probably a patch somewhere that adds totally awesome shutdown code in OOM cases, but afaics we just print a warning and exit right now... it is just stupid to do the checks in the real code then.

It's definately better than what we have now (no error checking at all), so:

thanks, r1370
A few notes for later though:
- We should call any shutdown function which may need to be called in the respective places (and any free()s which may be needed).
that would probably be handled by int programmer_shutdown(void) in flashrom.c at the moment. it should either be named differently or wrapped with a more generic function though(?)
- Later we should not exit(1) upon the error, but rather return an error code instead (e.g. FL_ERR_MALLOC or similar), at least in all public "API" functions which are meant to be in the upcoming libflashrom.
and in the internal ones? just as errors values?
- A small xmalloc() wrapper (or use another name) would indeed be nice, too, but once we really return error codes etc. it's not really useful anymore I think.
that's true, at least as long as it is not a macro that automagically returns on errors (which would be super evil, but... well no "but" i guess. :)
