Indicates there was a file error of some kind.

$ferr


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. }
