61 * SignalProc32 (USER.391)
62 * UserSignalProc (USER32.@)
64 * The exact meaning of the USER signals is undocumented, but this
65 * should cover the basic idea:
67 * USIG_DLL_UNLOAD_WIN16
68 * This is sent when a 16-bit module is unloaded.
70 * USIG_DLL_UNLOAD_WIN32
71 * This is sent when a 32-bit module is unloaded.
73 * USIG_DLL_UNLOAD_ORPHANS
74 * This is sent after the last Win3.1 module is unloaded,
75 * to allow removal of orphaned menus.
77 * USIG_FAULT_DIALOG_PUSH
78 * USIG_FAULT_DIALOG_POP
79 * These are called to allow USER to prepare for displaying a
80 * fault dialog, even though the fault might have happened while
81 * inside a USER critical section.
84 * This is called from the context of a new thread, as soon as it
88 * This is called, still in its context, just before a thread is
92 * This is called, in the parent process context, after a new process
96 * This is called in the new process context, just after the main thread
97 * has started execution (after the main thread's USIG_THREAD_INIT has
100 * USIG_PROCESS_LOADED
101 * This is called after the executable file has been loaded into the
102 * new process context.
104 * USIG_PROCESS_RUNNING
105 * This is called immediately before the main entry point is called.
108 * This is called in the context of a process that is about to
109 * terminate (but before the last thread's USIG_THREAD_EXIT has
112 * USIG_PROCESS_DESTROY
113 * This is called after a process has terminated.
116 * The meaning of the dwFlags bits is as follows:
119 * Current process is 32-bit.
122 * Current process is a (Win32) GUI process.
124 * USIG_FLAGS_FEEDBACK
125 * Current process needs 'feedback' (determined from the STARTUPINFO
126 * flags STARTF_FORCEONFEEDBACK / STARTF_FORCEOFFFEEDBACK).
129 * The signal is being sent due to a fault.
