49 * PROCESS_CallUserSignalProc
51 * FIXME: Some of the signals aren't sent correctly!
53 * The exact meaning of the USER signals is undocumented, but this
54 * should cover the basic idea:
56 * USIG_DLL_UNLOAD_WIN16
57 * This is sent when a 16-bit module is unloaded.
59 * USIG_DLL_UNLOAD_WIN32
60 * This is sent when a 32-bit module is unloaded.
62 * USIG_DLL_UNLOAD_ORPHANS
63 * This is sent after the last Win3.1 module is unloaded,
64 * to allow removal of orphaned menus.
66 * USIG_FAULT_DIALOG_PUSH
67 * USIG_FAULT_DIALOG_POP
68 * These are called to allow USER to prepare for displaying a
69 * fault dialog, even though the fault might have happened while
70 * inside a USER critical section.
73 * This is called from the context of a new thread, as soon as it
77 * This is called, still in its context, just before a thread is
81 * This is called, in the parent process context, after a new process
85 * This is called in the new process context, just after the main thread
86 * has started execution (after the main thread's USIG_THREAD_INIT has
90 * This is called after the executable file has been loaded into the
91 * new process context.
93 * USIG_PROCESS_RUNNING
94 * This is called immediately before the main entry point is called.
97 * This is called in the context of a process that is about to
98 * terminate (but before the last thread's USIG_THREAD_EXIT has
101 * USIG_PROCESS_DESTROY
102 * This is called after a process has terminated.
105 * The meaning of the dwFlags bits is as follows:
108 * Current process is 32-bit.
111 * Current process is a (Win32) GUI process.
113 * USIG_FLAGS_FEEDBACK
114 * Current process needs 'feedback' (determined from the STARTUPINFO
115 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
118 * The signal is being sent due to a fault.
