Description

From bruen...@google.com on December 05, 2012 19:41:53

the official return type is DWORD_PTR but it would be more useful to give the actual types

Contributor guide

Research direction
Investigate the NtUserCall* secondary syscalls in Windows to determine their actual return types, then update the relevant code in drmemory to reflect these types. Consult Windows documentation or use reverse engineering tools to identify the correct types for each syscall variant.
