#include <cstdio> int fseek( FILE *stream, long offset, int origin );
The function fseek() sets the file position data for the given stream. The origin value should have one of the following values (defined in cstdio):
|SEEK_SET||Seek from the start of the file|
|SEEK_CUR||Seek from the current location|
|SEEK_END||Seek from the end of the file|
fseek() returns zero upon success, non-zero on failure. You can use fseek() to move beyond a file, but not before the beginning. Using fseek() clears the EOF flag associated with that stream.
