/***********************************************************
Win32 emulation code. Functions that emulate
responses from corresponding Win32 API calls.
Since we are not going to be able to load
virtually any DLL, we can only implement this
much, adding needed functions with each new codec.
Basic principle of implementation: it's not good
for DLL to know too much about its environment.

From GetCurrentThread() documentation:
A pseudo handle is a special constant that is interpreted as the current thread handle. The calling thread can use this handle to specify itself whenever a thread handle is required. Pseudo handles are not inherited by child processes.
This handle has the maximum possible access to the thread object. For systems that support security descriptors, this is the maximum access allowed by the security descriptor for the calling process. For systems that do not support security descriptors, this is THREAD_ALL_ACCESS.
The function cannot be used by one thread to create a handle that can be used by other threads to refer to the first thread. The handle is always interpreted as referring to the thread that is using it. A thread can create a "real" handle to itself that can be used by other threads, or inherited by other processes, by specifying the pseudo handle as the source handle in a call to the DuplicateHandle function.
