fsetpos(3S)
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(3S) 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(3S) 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 an explicit 64-bit equivalent. See interface64(5).
