NAME

zkFsetpos - set current file position

SYNOPSIS

#include "zkStdio.h"

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

DESCRIPTION

The zkFsetpos() function sets the file position and state indicators 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 zkFgetpos() on the same stream.

A successful call to zkFsetpos() function clears the end-of-file indicator for the stream and undoes any effects of ungetc() on the same stream. After an zkFsetpos() call, the next operation on an update stream may be either input or output.

RETURN VALUE

The zkFsetpos() function returns 0 if it succeeds; otherwise it returns a non-zero value and sets errno to indicate the error.

ERRORS

The zkFsetpos() function may fail if:

[EBADF]
The file descriptor underlying stream is not valid.
[ESPIPE]
The file descriptor underlying stream is associated with a pipe or FIFO.
