fseek
=====

Syntax
------

     #include <stdio.h>
     
     int fseek(FILE *file, long offset, int mode);

Description
-----------

This function moves the file pointer for FILE according to MODE:

`SEEK_SET'
     The file pointer is moved to the offset specified.

`SEEK_CUR'
     The file pointer is moved relative to its current position.

`SEEK_END'
     The file pointer is moved to a position OFFSET bytes from the end
     of the file.  The offset is usually nonpositive in this case.

*Warning!* The ANSI standard only allows values of zero for OFFSET when
WHENCE is not `SEEK_SET' and the file has been opened as a text file.
Although this restriction is not enforced, beware that there is not a
one-to-one correspondence between file characters and text characters
under MS-DOS, so some `fseek' operations may not do exactly what you
expect.

Return Value
------------

Zero if successful, nonzero if not.

Example
-------

     fseek(stdin, 12, SEEK_CUR); /* skip 12 bytes */
