NAME

       explain_fseek_or_die - reposition a stream and report errors

SYNOPSIS

       #include <libexplain/fseek.h>
       void explain_fseek_or_die(FILE *fp, long offset, int whence);
       int explain_fseek_on_error(FILE *fp, long offset, int whence);

DESCRIPTION

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

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

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

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

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

RETURN VALUE

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

       The explain_fseek_on_error function  always  returns  the  value  return  by  the  wrapped
       fseek(3) system call.

EXAMPLE

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