NAME

       explain_fseeko_or_die - seek to or report file position and report errors

SYNOPSIS

       #include <libexplain/fseeko.h>
       void explain_fseeko_or_die(FILE *fp, off_t offset, int whence);
       int explain_fseeko_on_error(FILE *fp, off_t offset, int whence);

DESCRIPTION

       The  explain_fseeko_or_die  function is used to call the fseeko(3) system call. On failure
       an explanation will be printed to stderr, obtained from  the  explain_fseeko(3)  function,
       and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_fseeko_on_error function is used to call the fseeko(3) system call. On failure
       an explanation will be printed to stderr, obtained from  the  explain_fseeko(3)  function,
       but still returns to the caller.

       fp      The fp, exactly as to be passed to the fseeko(3) system call.

       offset  The offset, exactly as to be passed to the fseeko(3) system call.

       whence  The whence, exactly as to be passed to the fseeko(3) system call.

RETURN VALUE

       The  explain_fseeko_or_die  function  only  returns  on  success,  see  fseeko(3) for more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_fseeko_on_error function always  returns  the  value  return  by  the  wrapped
       fseeko(3) system call.

EXAMPLE

       The  explain_fseeko_or_die  function  is  intended  to be used in a fashion similar to the
       following example:
              explain_fseeko_or_die(fp, offset, whence);
