Subject: Restrict this function to a max of 65k io vectors to avoid weird
X-Git-Tag: php-4.3.2RC2~251
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f461ad12fba175b705923981a48d8a41278783a3;p=php

Restrict this function to a max of 65k io vectors to avoid weird
overflows.  Purely an arbitrary number.  This API needs cleaning up,
but it would break BC and I don't want to do that in 4.3.
