Clib.fseek() Method

This method sets the position of the file cursor of an open file.

Syntax

Clib.fseek(filePointer, offset[, mode])

Parameter
Description

filePointer

A file pointer as returned by Clib.fopen()

offset

The number of bytes to move the file cursor beyond mode

mode

One of the following values:

SEEK_CUR: seek is relative to the current position of the file cursor

SEEK_END: seek is relative to the end of the file

SEEK_SET: seek is relative to the beginning of the file
Returns

0 if successful, or nonzero if it cannot set the file cursor to the indicated position.

Usage

This method sets the position of the file cursor in the file indicated by filePointer. If mode is not supplied, then the absolute offset from the beginning of the file (SEEK_SET) is assumed. For text files (that is, files not opened in binary mode), the file position may not correspond exactly to the byte offset in the file.
