Description

From bruen...@google.com on December 05, 2012 19:39:38

issue #1090 is adding return value types to all the syscalls. notskrnl are all NTSTATUS, but NtUser and NtGdi have a lot of different types. many are integer types. we're going to need to individually look up their failure codes (i.e., whether 0 indicates failure, or -1, or < 0, or what).
