Overview
#include <stdio.h>

r = fseek(f,offset,mode);

int r;
FILE *f;
long offset;
int mode;

Portability

Description
This function moves the byte cursor of the file referred to by "f" to a new position. "offset" is the offset relative to the seek position specified by "mode".

Allowed values for "mode" are:
SEEK_CUR: The offset is based relative to the current position and can thus be either positive or negative.
SEEK_SET: The offset is based relative to the start of the file and should thus be positive.
SEEK_END: The offset is based relative to the end of the file and should thus be negative.

Returns
If an error occured, zero is returned, otherwise a value unequal zero.
