144 * This is sent when a 32-bit module is unloaded.
146 * USIG_DLL_UNLOAD_ORPHANS
147 * This is sent after the last Win3.1 module is unloaded,
148 * to allow removal of orphaned menus.
150 * USIG_FAULT_DIALOG_PUSH
151 * USIG_FAULT_DIALOG_POP
152 * These are called to allow USER to prepare for displaying a
153 * fault dialog, even though the fault might have happened while
154 * inside a USER critical section.
157 * This is called from the context of a new thread, as soon as it
158 * has started to run.
161 * This is called, still in its context, just before a thread is
162 * about to terminate.
164 * USIG_PROCESS_CREATE
165 * This is called, in the parent process context, after a new process
169 * This is called in the new process context, just after the main thread
170 * has started execution (after the main thread's USIG_THREAD_INIT has
173 * USIG_PROCESS_LOADED
174 * This is called after the executable file has been loaded into the
175 * new process context.
177 * USIG_PROCESS_RUNNING
178 * This is called immediately before the main entry point is called.
181 * This is called in the context of a process that is about to
182 * terminate (but before the last thread's USIG_THREAD_EXIT has
185 * USIG_PROCESS_DESTROY
186 * This is called after a process has terminated.
189 * The meaning of the dwFlags bits is as follows:
192 * Current process is 32-bit.
195 * Current process is a (Win32) GUI process.
197 * USIG_FLAGS_FEEDBACK
198 * Current process needs 'feedback' (determined from the STARTUPINFO
199 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
202 * The signal is being sent due to a fault.
