fsetpos(3C)          COMPATIBILITY FUNCTIONS          fsetpos(3C)



NAME
     fsetpos, fgetpos - reposition a file pointer in a stream

SYNOPSIS
     #include <stdio.h>

     int fsetpos (FILE *stream, const fpos_t *pos);

     int fgetpos (FILE *stream, fpos_t *pos);

DESCRIPTION
     fsetpos sets the position of the next input or output opera-
     tion  on  the  stream  according  to the value of the object
     pointed to by pos.  The object pointed to by pos must  be  a
     value  returned  by  an  earlier call to fgetpos on the same
     stream.

     fsetpos clears the end-of-file indicator for the stream  and
     undoes  any  effects  of  the  ungetc  function  on the same
     stream. After fsetpos, the next operation on a  file  opened
     for update may be either input or output.

     fgetpos stores the current value of the file position  indi-
     cator for stream in the object pointed to by pos.  The value
     stored contains information usable by  fsetpos  for  reposi-
     tioning  the  stream to its position at the time of the call
     to fgetpos.

     If successful, both fsetpos and fgetpos return zero.  Other-
     wise, they both return nonzero.
