NAME
       explain_fsetpos_or_die - reposition a stream and report errors

SYNOPSIS
       #include <libexplain/fsetpos.h>
       void explain_fsetpos_or_die(FILE *fp, fpos_t *pos);
       int explain_fsetpos_on_error(FILE *fp, fpos_t *pos);

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

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

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

       pos     The pos, exactly as to be passed to the fsetpos(3) system call.

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

       The explain_fsetpos_on_error function always returns the value return by the wrapped fsetpos(3) system call.

EXAMPLE
       The explain_fsetpos_or_die function is intended to be used in a fashion similar to the following example:
	      explain_fsetpos_or_die(fp, pos);
