NAME

       explain_fgetpos_or_die - reposition a stream and report errors

SYNOPSIS

       #include <libexplain/fgetpos.h>
       void explain_fgetpos_or_die(FILE *fp, fpos_t *pos);
       int explain_fgetpos_on_error(FILE *fp, fpos_t *pos);

DESCRIPTION

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

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

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

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

RETURN VALUE

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

       The explain_fgetpos_on_error function always returns  the  value  return  by  the  wrapped
       fgetpos(3) system call.

EXAMPLE

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