47 * PROCESS_CallUserSignalProc
49 * FIXME: Some of the signals aren't sent correctly!
51 * The exact meaning of the USER signals is undocumented, but this
52 * should cover the basic idea:
54 * USIG_DLL_UNLOAD_WIN16
55 * This is sent when a 16-bit module is unloaded.
57 * USIG_DLL_UNLOAD_WIN32
58 * This is sent when a 32-bit module is unloaded.
60 * USIG_DLL_UNLOAD_ORPHANS
61 * This is sent after the last Win3.1 module is unloaded,
62 * to allow removal of orphaned menus.
64 * USIG_FAULT_DIALOG_PUSH
65 * USIG_FAULT_DIALOG_POP
66 * These are called to allow USER to prepare for displaying a
67 * fault dialog, even though the fault might have happened while
68 * inside a USER critical section.
71 * This is called from the context of a new thread, as soon as it
75 * This is called, still in its context, just before a thread is
79 * This is called, in the parent process context, after a new process
83 * This is called in the new process context, just after the main thread
84 * has started execution (after the main thread's USIG_THREAD_INIT has
88 * This is called after the executable file has been loaded into the
89 * new process context.
91 * USIG_PROCESS_RUNNING
92 * This is called immediately before the main entry point is called.
95 * This is called in the context of a process that is about to
96 * terminate (but before the last thread's USIG_THREAD_EXIT has
99 * USIG_PROCESS_DESTROY
100 * This is called after a process has terminated.
103 * The meaning of the dwFlags bits is as follows:
106 * Current process is 32-bit.
109 * Current process is a (Win32) GUI process.
111 * USIG_FLAGS_FEEDBACK
112 * Current process needs 'feedback' (determined from the STARTUPINFO
113 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
116 * The signal is being sent due to a fault.
