  () contains RCINFO.ProcFlags that can be set and help to identify error.

  ErrorAHSuccess   - general code for success.
                     This code is returned by (h)EstablishApiHooks and HookApi
                     functions when hooks were successfully applied or Hooks_DLL
                     is already present in Target.

  ErrorAHException - AH function was called with invalid parameter(s).
                     String passed to Mod/ApiWorks has more than MAX_PATH-1
                     characters ().
                     More than 20 parameters were passed to (h)LoadAndCall ().

  ErrorAHOpen      - can't open process represented by ProcessId or hProcess.
                     ProcessId or hProcess are invalid (RC_PF_NOOPEN).
                     9x: Process is 16bit or terminating/terminated (RC_PF_16TERM).
                     NT: Security: can't open for QR (RC_PF_NOOPEN).
                     NT: Security: can't open for QRWOT(C) ().

  ErrorAHPrepare   - error when preparing remote execution.
                     AH can't allocate memory in current process or in Target ().
                     Target's memory can't be written to ().
                     Remote thread can't be created in Target ('System' process) ().

  ErrorAHTimeOut   - time has expired but thread hasn't returned yet.
                     Part of remote code could be executed.
                     Typically, remote thread waits for critical section.
                     Target is debugged (RC_PF_DEBUGGED).

  ErrorAHRemote    - general code for unsuccess, remote execution wasn't successful.
                     Target doesn't contain KERNEL32.dll or the pointers to
                     required APIs are invalid in Target (RC_PF_NATIVE).
                     Remote thread raised an exception.
                     (h)EstablishApiHooks can return this code when
                     Hooks_DLL can't be loaded (no memory, impresence.
                     of imported dlls (e.g. ApiHooks.dll) in search path, ...)
                     Hooks_DLL's DllMain faulted or returned FALSE.
                     ApiHookChain in Hooks_DLL is invalid, not present or
                     not writable.
