123 * USIG_DLL_UNLOAD_WIN16
124 * This is sent when a 16-bit module is unloaded.
126 * USIG_DLL_UNLOAD_WIN32
127 * This is sent when a 32-bit module is unloaded.
129 * USIG_DLL_UNLOAD_ORPHANS
130 * This is sent after the last Win3.1 module is unloaded,
131 * to allow removal of orphaned menus.
133 * USIG_FAULT_DIALOG_PUSH
134 * USIG_FAULT_DIALOG_POP
135 * These are called to allow USER to prepare for displaying a
136 * fault dialog, even though the fault might have happened while
137 * inside a USER critical section.
140 * This is called from the context of a new thread, as soon as it
141 * has started to run.
144 * This is called, still in its context, just before a thread is
145 * about to terminate.
147 * USIG_PROCESS_CREATE
148 * This is called, in the parent process context, after a new process
152 * This is called in the new process context, just after the main thread
153 * has started execution (after the main thread's USIG_THREAD_INIT has
156 * USIG_PROCESS_LOADED
157 * This is called after the executable file has been loaded into the
158 * new process context.
160 * USIG_PROCESS_RUNNING
161 * This is called immediately before the main entry point is called.
164 * This is called in the context of a process that is about to
165 * terminate (but before the last thread's USIG_THREAD_EXIT has
168 * USIG_PROCESS_DESTROY
169 * This is called after a process has terminated.
172 * The meaning of the dwFlags bits is as follows:
175 * Current process is 32-bit.
178 * Current process is a (Win32) GUI process.
180 * USIG_FLAGS_FEEDBACK
181 * Current process needs 'feedback' (determined from the STARTUPINFO
182 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
185 * The signal is being sent due to a fault.
