lseek() lets you specify new file offsets past the current end of the file. If data is written at such a point, read operations in the gap between this data and the old end of the file will return bytes containing zeros. The lseek() function allows the file offset to be set beyond the end of the file (but this does not change the size of the file).

The lseek () family of functions reposition the offset of the open file associated with the file descriptor fd to offset bytes relative to the start, current position, or end of the file, when whence has the value SEEK_SET, SEEK_CUR, or SEEK_END, respectively. For more details, return value, and errors, see lseek (2).

Tutorial should also be applicable in C/UNIX programming. An example on how to use the lseek() function The lseek () family of functions reposition the offset of the open file associated with the file descriptor fd to offset bytes relative to the start, current position, or end of the file, when whence has the value SEEK_SET, SEEK_CUR, or SEEK_END, respectively. For more details, return value, and errors, see lseek (2). The character l in the name lseek means ‘‘long integer.’’ Before the introduction of the off_t data type, the offset argument and the return value were long integers.

# include /* for printf */. I know what lseek does, but i need an example with simple positioning and reading the file after positioning for 5 bytes from the beggining(the whole code) not a line like : lseek(..) and what is it for. If anyone have some simple code for example I 'd be greatfull I believe lseek() is a POSIX extension, and not a part of standard ANSI-C. # RDOS operating system # Copyright (C) 1988-2006, Leif Ekblad # # This library is free software; you can redistribute it and/or modify # it under the terms of the The lseek() function allows the file offset to be set beyond the end of existing data in the file.
