NAME

       pack_ferror - Tells if an error occurred during an operation on the stream. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int pack_ferror(PACKFILE *f);

DESCRIPTION

       Since EOF is used to report errors by some functions, it's often better to use the pack_feof() function to check explicitly for end of file
       and pack_ferror() to check for errors. Both functions check indicators that are part of the internal state of the  stream  to  detect  cor-
       rectly the different situations.

RETURN VALUE

       Returns nonzero if the error indicator for the stream is set, meaning that an error has occurred during a previous operation on the stream.
