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);
