fsetpos(3C)            UNIX System V(C Development Set)             fsetpos(3C)


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

SYNOPSIS
      #include <stdio.h>

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

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

DESCRIPTION
      fsetpos sets the position of the next input or output operation 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 indicator for
      stream in the object pointed to by pos.  The value stored contains
      information usable by fsetpos for repositioning the stream to its
      position at the time of the call to fgetpos.

      If successful, both fsetpos and fgetpos return zero. Otherwise, they both
      return nonzero.
