FSETPOS(3C) Standard C Library Functions FSETPOS(3C)
NAME
fsetpos - reposition a file pointer in a stream
SYNOPSIS
#include <stdio.h>
int fsetpos(
FILE *stream,
const fpos_t *pos);
DESCRIPTION
The
fsetpos() function sets 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 obtained from an earlier
call to
fgetpos(3C) on the same stream.
A successful call to
fsetpos() function clears the end-of-file
indicator for the stream and undoes any effects of
ungetc(3C) on the
same stream. After an
fsetpos() call, the next operation on an
update stream may be either input or output.
RETURN VALUES
The
fsetpos() function returns
0 if it succeeds; otherwise it returns
a non-zero value and sets
errno to indicate the error.
ERRORS
The
fsetpos() function may fail if:
EBADF The file descriptor underlying
stream is not valid.
ESPIPE The file descriptor underlying
stream is associated with a
pipe, a FIFO, or a socket.
USAGE
The
fsetpos() function has a transitional interface for 64-bit file
offsets. See
lf64(7).
