Subject: linux-user: Use target abi_int type for pipefd[1] in pipe()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=6f200f51869ff0de7ea0343dd7104362e994b382;p=qmiga%2Fqemu.git

linux-user: Use target abi_int type for pipefd[1] in pipe()

When writing back the fd[1] pipe file handle to emulated userspace
memory, use sizeof(abi_int) as offset insted of the hosts's int type.
There is no functional change in this patch.
