109 * USIG_DLL_UNLOAD_WIN16
110 * This is sent when a 16-bit module is unloaded.
112 * USIG_DLL_UNLOAD_WIN32
113 * This is sent when a 32-bit module is unloaded.
115 * USIG_DLL_UNLOAD_ORPHANS
116 * This is sent after the last Win3.1 module is unloaded,
117 * to allow removal of orphaned menus.
119 * USIG_FAULT_DIALOG_PUSH
120 * USIG_FAULT_DIALOG_POP
121 * These are called to allow USER to prepare for displaying a
122 * fault dialog, even though the fault might have happened while
123 * inside a USER critical section.
126 * This is called from the context of a new thread, as soon as it
127 * has started to run.
130 * This is called, still in its context, just before a thread is
131 * about to terminate.
133 * USIG_PROCESS_CREATE
134 * This is called, in the parent process context, after a new process
138 * This is called in the new process context, just after the main thread
139 * has started execution (after the main thread's USIG_THREAD_INIT has
142 * USIG_PROCESS_LOADED
143 * This is called after the executable file has been loaded into the
144 * new process context.
146 * USIG_PROCESS_RUNNING
147 * This is called immediately before the main entry point is called.
150 * This is called in the context of a process that is about to
151 * terminate (but before the last thread's USIG_THREAD_EXIT has
154 * USIG_PROCESS_DESTROY
155 * This is called after a process has terminated.
158 * The meaning of the dwFlags bits is as follows:
161 * Current process is 32-bit.
164 * Current process is a (Win32) GUI process.
166 * USIG_FLAGS_FEEDBACK
167 * Current process needs 'feedback' (determined from the STARTUPINFO
168 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
171 * The signal is being sent due to a fault.
