 fgetpos(3S)                                                     fgetpos(3S)





 NAME
      fgetpos(), fsetpos() - save and restore a file position indicator for
      a stream

 SYNOPSIS
      #include <stdio.h>

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

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

 DESCRIPTION
      fgetpos()      Store the current value of the file position indicator
                     for the stream pointed to by 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().

      fsetpos()      Set the file position indicator for the stream pointed
                     to by stream according to the value of the object
                     pointed to by pos, which must be a value set by an
                     earlier call to fgetpos() on the same stream.

                     A successful call to fsetpos() clears the end-of-file
                     indicator for the stream and undoes any effects of
                     ungetc(3S) on the same stream.  After a fsetpos() call,
                     the next operation on a update stream can be either
                     input or output.

 RETURN VALUE
      If successful, these functions return zero; otherwise non-zero.

 WARNINGS
      Failure can occur if these functions are used on a file that has not
      been opened via fopen().  In particular, they must not be used on a
      terminal or on a file opened via popen(3S).

      fsetpos() has no effect on streams that are open for append (see
      fopen(3S)).

 SEE ALSO
      fseek(3S), fopen(3S), popen(3S), ungetc(3S).
