Declaration:
int fseek(FILE *stream, long intoffset, intwhence);

SEEK_SET | Seeks from the beginning of the file. |
SEEK_CUR | Seeks from the current position. |
SEEK_END | Seeks from the end of the file. |
On a text stream, whence should be SEEK_SET and offset should be either zero or a value returned from ftell.
The end-of-file indicator is reset. The error indicator is NOT reset.
On success zero is returned. On error a nonzero value is returned.
