127 * USIG_DLL_UNLOAD_WIN32
128 * This is sent when a 32-bit module is unloaded.
130 * USIG_DLL_UNLOAD_ORPHANS
131 * This is sent after the last Win3.1 module is unloaded,
132 * to allow removal of orphaned menus.
134 * USIG_FAULT_DIALOG_PUSH
135 * USIG_FAULT_DIALOG_POP
136 * These are called to allow USER to prepare for displaying a
137 * fault dialog, even though the fault might have happened while
138 * inside a USER critical section.
141 * This is called from the context of a new thread, as soon as it
142 * has started to run.
145 * This is called, still in its context, just before a thread is
146 * about to terminate.
148 * USIG_PROCESS_CREATE
149 * This is called, in the parent process context, after a new process
153 * This is called in the new process context, just after the main thread
154 * has started execution (after the main thread's USIG_THREAD_INIT has
157 * USIG_PROCESS_LOADED
158 * This is called after the executable file has been loaded into the
159 * new process context.
161 * USIG_PROCESS_RUNNING
162 * This is called immediately before the main entry point is called.
165 * This is called in the context of a process that is about to
166 * terminate (but before the last thread's USIG_THREAD_EXIT has
169 * USIG_PROCESS_DESTROY
170 * This is called after a process has terminated.
173 * The meaning of the dwFlags bits is as follows:
176 * Current process is 32-bit.
179 * Current process is a (Win32) GUI process.
181 * USIG_FLAGS_FEEDBACK
182 * Current process needs 'feedback' (determined from the STARTUPINFO
183 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
186 * The signal is being sent due to a fault.
