Returns 1 if an error occurred, 0 else.
Example
; we open a file we probably don't have, but silently (the dot infront of the command) .fopen moo we_dont_have_this_file.txt ; check whether $ferr returns 1 (true) and echo it if ($ferr) { echo -a An error occurred. } ; else echo that no error occurred. else { echo -a No error occurred. }
