#47371 [NEW]: fseek: Description of negative offset use is not clear
From: sammywg@php.net
Operating system:
PHP version: Irrelevant
PHP Bug Type: Documentation problem
Bug description: fseek: Description of negative offset use is not clear
Description:
------------
If you want to use negative fseek offset, it is not enough to use a
negative offset as second parameter, also the third parameter must be
specified as SEEK_END. The documentation should note that fact, currently
it appears as if a function call like
$i = fseek($filehandle, -100);
would be adequate.
Reproduce code:
---------------
http://php.net/fseek
Expected result:
----------------
To move to a position before the end-of-file, you need to pass a negative
value in offset and set the whence parameter to SEEK_END.
Actual result:
--------------
To move to a position before the end-of-file, you need to pass a negative
value in offset .
