160 * USIG_DLL_UNLOAD_WIN16
161 * This is sent when a 16-bit module is unloaded.
163 * USIG_DLL_UNLOAD_WIN32
164 * This is sent when a 32-bit module is unloaded.
166 * USIG_DLL_UNLOAD_ORPHANS
167 * This is sent after the last Win3.1 module is unloaded,
168 * to allow removal of orphaned menus.
170 * USIG_FAULT_DIALOG_PUSH
171 * USIG_FAULT_DIALOG_POP
172 * These are called to allow USER to prepare for displaying a
173 * fault dialog, even though the fault might have happened while
174 * inside a USER critical section.
177 * This is called from the context of a new thread, as soon as it
178 * has started to run.
181 * This is called, still in its context, just before a thread is
182 * about to terminate.
184 * USIG_PROCESS_CREATE
185 * This is called, in the parent process context, after a new process
189 * This is called in the new process context, just after the main thread
190 * has started execution (after the main thread's USIG_THREAD_INIT has
193 * USIG_PROCESS_LOADED
194 * This is called after the executable file has been loaded into the
195 * new process context.
197 * USIG_PROCESS_RUNNING
198 * This is called immediately before the main entry point is called.
201 * This is called in the context of a process that is about to
202 * terminate (but before the last thread's USIG_THREAD_EXIT has
205 * USIG_PROCESS_DESTROY
206 * This is called after a process has terminated.
209 * The meaning of the dwFlags bits is as follows:
212 * Current process is 32-bit.
215 * Current process is a (Win32) GUI process.
217 * USIG_FLAGS_FEEDBACK
218 * Current process needs 'feedback' (determined from the STARTUPINFO
219 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
222 * The signal is being sent due to a fault.
