From b6cdcc994062fb93affd9d473219a5f06d4029ff Mon Sep 17 00:00:00 2001 From: jhb Date: Thu, 3 Dec 2009 15:14:30 +0000 Subject: The fd_mask type is an unsigned long, not an int, so treat the mask as a long instead of an int when examining the results of select() to look for RPC requests. Previously this routine would ignore RPC requests to sockets whose file descriptor mod 64 was greater than 31 on a 64-bit platform.
