#3 Check return codes everywhere

[Anonymous]

Some checks for return codes are missing.

Examples:
Would you like to add more error handling for return values from "fputs" like in the function "save_image" and from "pthread_join" in the function "Pt_Stop"?

I suggest to avoid unchecked function calls.
Would you like to detect every error situation as early as possible?

pthread_join no longer has fputs
save_image now checks return value from fopen. Since save_image is really for debugging, I don't think it's worth it to install better error handling -- if you run out of disk here, you have bigger problems (but I'll patch the code if you feel something better is really needed and you want to implement it).
