119 * SignalProc32 (USER.391)
120 * UserSignalProc (USER32.@)
122 * The exact meaning of the USER signals is undocumented, but this
123 * should cover the basic idea:
125 * USIG_DLL_UNLOAD_WIN16
126 * This is sent when a 16-bit module is unloaded.
128 * USIG_DLL_UNLOAD_WIN32
129 * This is sent when a 32-bit module is unloaded.
131 * USIG_DLL_UNLOAD_ORPHANS
132 * This is sent after the last Win3.1 module is unloaded,
133 * to allow removal of orphaned menus.
135 * USIG_FAULT_DIALOG_PUSH
136 * USIG_FAULT_DIALOG_POP
137 * These are called to allow USER to prepare for displaying a
138 * fault dialog, even though the fault might have happened while
139 * inside a USER critical section.
142 * This is called from the context of a new thread, as soon as it
143 * has started to run.
146 * This is called, still in its context, just before a thread is
147 * about to terminate.
149 * USIG_PROCESS_CREATE
150 * This is called, in the parent process context, after a new process
154 * This is called in the new process context, just after the main thread
155 * has started execution (after the main thread's USIG_THREAD_INIT has
158 * USIG_PROCESS_LOADED
159 * This is called after the executable file has been loaded into the
160 * new process context.
162 * USIG_PROCESS_RUNNING
163 * This is called immediately before the main entry point is called.
166 * This is called in the context of a process that is about to
167 * terminate (but before the last thread's USIG_THREAD_EXIT has
170 * USIG_PROCESS_DESTROY
171 * This is called after a process has terminated.
174 * The meaning of the dwFlags bits is as follows:
177 * Current process is 32-bit.
180 * Current process is a (Win32) GUI process.
182 * USIG_FLAGS_FEEDBACK
183 * Current process needs 'feedback' (determined from the STARTUPINFO
184 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
187 * The signal is being sent due to a fault.
