30 /* There is one object called an event_stream. This object contains
|
|
|
31 callback functions for doing the window-system-dependent operations
|
|
|
32 that XEmacs requires.
|
|
|
33
|
|
|
34 If XEmacs is compiled with support for X11 and the X Toolkit, then this
|
|
|
35 event_stream structure will contain functions that can cope with input
|
|
|
36 on XEmacs windows on multiple displays, as well as input from dumb tty
|
|
|
37 frames.
|
|
|
38
|
|
|
39 If it is desired to have XEmacs able to open frames on the displays of
|
|
|
40 multiple heterogeneous machines, X11 and SunView, or X11 and NeXT, for
|
|
|
41 example, then it will be necessary to construct an event_stream structure
|
|
|
42 that can cope with the given types. Currently, the only implemented
|
|
440
|
43 event_streams are for dumb-ttys, and for X11 plus dumb-ttys,
|
|
|
44 and for mswindows.
|
|
428
|
45
|
|
|
46 To implement this for one window system is relatively simple.
|
|
|
47 To implement this for multiple window systems is trickier and may
|
|
|
48 not be possible in all situations, but it's been done for X and TTY.
|
|
|
49
|
|
|
50 Note that these callbacks are *NOT* console methods; that's because
|
|
|
51 the routines are not specific to a particular console type but must
|
|
|
52 be able to simultaneously cope with all allowable console types.
|
|
|
53
|
|
|
54 The slots of the event_stream structure:
|
|
|
55
|
|
|
56 next_event_cb A function which fills in an XEmacs_event structure
|
|
|
57 with the next event available. If there is no event
|
|
|
58 available, then this should block.
|
|
|
59
|
|
|
60 IMPORTANT: timer events and especially process
|
|
|
61 events *must not* be returned if there are
|
|
|
62 events of other types available; otherwise you
|
|
|
63 can end up with an infinite loop in Fdiscard_input().
|
|
|
64
|
|
|
65 event_pending_cb A function which says whether there are events to be
|
|
|
66 read. If called with an argument of 0, then this
|
|
|
67 should say whether calling the next_event_cb will
|
|
1268
|
68 block. If called with a non-zero argument, then this
|
|
|
69 should say whether there are that many user-generated
|
|
|
70 events pending (that is, keypresses, mouse-clicks,
|
|
|
71 dialog-box selection events, etc.). (This is used for
|
|
|
72 redisplay optimization, among other things.) The
|
|
|
73 difference is that the former includes process events
|
|
|
74 and timer events, but the latter doesn't.
|
|
428
|
75
|
|
|
76 If this function is not sure whether there are events
|
|
|
77 to be read, it *must* return 0. Otherwise various
|
|
|
78 undesirable effects will occur, such as redisplay
|
|
|
79 not occurring until the next event occurs.
|
|
|
80
|
|
|
81 handle_magic_event_cb XEmacs calls this with an event structure which
|
|
|
82 contains window-system dependent information that
|
|
|
83 XEmacs doesn't need to know about, but which must
|
|
|
84 happen in order. If the next_event_cb never returns
|
|
|
85 an event of type "magic", this will never be used.
|
|
|
86
|
|
788
|
87 format_magic_event_cb Called with a magic event; print a representation of
|
|
|
88 the innards of the event to PSTREAM.
|
|
|
89
|
|
|
90 compare_magic_event_cb Called with two magic events; return non-zero if
|
|
|
91 the innards of the two are equal, zero otherwise.
|
|
|
92
|
|
|
93 hash_magic_event_cb Called with a magic event; return a hash of the
|
|
|
94 innards of the event.
|
|
|
95
|
|
428
|
96 add_timeout_cb Called with an EMACS_TIME, the absolute time at
|
|
|
97 which a wakeup event should be generated; and a
|
|
|
98 void *, which is an arbitrary value that will be
|
|
|
99 returned in the timeout event. The timeouts
|
|
|
100 generated by this function should be one-shots:
|
|
|
101 they fire once and then disappear. This callback
|
|
|
102 should return an int id-number which uniquely
|
|
|
103 identifies this wakeup. If an implementation
|
|
|
104 doesn't have microseconds or millisecond
|
|
|
105 granularity, it should round up to the closest
|
|
|
106 value it can deal with.
|
|
|
107
|
|
|
108 remove_timeout_cb Called with an int, the id number of a wakeup to
|
|
|
109 discard. This id number must have been returned by
|
|
|
110 the add_timeout_cb. If the given wakeup has
|
|
|
111 already expired, this should do nothing.
|
|
|
112
|
|
|
113 select_process_cb These callbacks tell the underlying implementation to
|
|
|
114 unselect_process_cb add or remove a file descriptor from the list of fds
|
|
|
115 which are polled for inferior-process input. When
|
|
|
116 input becomes available on the given process
|
|
|
117 connection, an event of type "process" should be
|
|
|
118 generated.
|
|
|
119
|
|
|
120 select_console_cb These callbacks tell the underlying implementation
|
|
|
121 unselect_console_cb to add or remove a console from the list of consoles
|
|
|
122 which are polled for user-input.
|
|
|
123
|
|
|
124 select_device_cb These callbacks are used by Unixoid event loops
|
|
|
125 unselect_device_cb (those that use select() and file descriptors and
|
|
|
126 have a separate input fd per device).
|
|
|
127
|
|
853
|
128 create_io_streams_cb These callbacks are called by process code to
|
|
|
129 delete_io_streams_cb create the input and output lstreams which are used
|
|
|
130 for subprocess I/O.
|
|
428
|
131
|
|
|
132 quitp_cb A handler function called from the `QUIT' macro which
|
|
|
133 should check whether the quit character has been
|
|
|
134 typed. On systems with SIGIO, this will not be called
|
|
|
135 unless the `sigio_happened' flag is true (it is set
|
|
|
136 from the SIGIO handler).
|
|
|
137
|
|
|
138 XEmacs has its own event structures, which are distinct from the event
|
|
|
139 structures used by X or any other window system. It is the job of the
|
|
|
140 event_stream layer to translate to this format.

144 Stream pairs description
|
|
|
145 ------------------------
|
|
|
146
|
|
1204
|
147 Since there are many possible processes/event loop combinations, the
|
|
|
148 event code is responsible for creating an appropriate lstream type. The
|
|
|
149 process implementation does not care about that implementation.
|
|
428
|
150
|
|
1204
|
151 The Create stream pair function is passed two void* values, which
|
|
|
152 identify process-dependent 'handles'. The process implementation uses
|
|
|
153 these handles to communicate with child processes. The function must be
|
|
|
154 prepared to receive handle types of any process implementation. Since
|
|
|
155 only one process implementation exists in a particular XEmacs
|
|
|
156 configuration, preprocessing is a means of compiling in the support for
|
|
|
157 the code which deals with particular handle types.
|
|
428
|
158
|
|
|
159 For example, a unixoid type loop, which relies on file descriptors, may be
|
|
|
160 asked to create a pair of streams by a unix-style process implementation.
|
|
|
161 In this case, the handles passed are unix file descriptors, and the code
|
|
|
162 may deal with these directly. Although, the same code may be used on Win32
|
|
|
163 system with X-Windows. In this case, Win32 process implementation passes
|
|
853
|
164 handles of type HANDLE, and the create_io_streams function must call
|
|
428
|
165 appropriate function to get file descriptors given HANDLEs, so that these
|
|
|
166 descriptors may be passed to XtAddInput.
|
|
|
167
|
|
|
168 The handle given may have special denying value, in which case the
|
|
|
169 corresponding lstream should not be created.
|
|
|
170
|
|
|
171 The return value of the function is a unique stream identifier. It is used
|
|
|
172 by processes implementation, in its platform-independent part. There is
|
|
|
173 the get_process_from_usid function, which returns process object given its
|
|
|
174 USID. The event stream is responsible for converting its internal handle
|
|
|
175 type into USID.
|
|
|
176
|
|
|
177 Example is the TTY event stream. When a file descriptor signals input, the
|
|
|
178 event loop must determine process to which the input is destined. Thus,
|
|
|
179 the implementation uses process input stream file descriptor as USID, by
|
|
|
180 simply casting the fd value to USID type.
|
|
|
181
|
|
|
182 There are two special USID values. One, USID_ERROR, indicates that the stream
|
|
|
183 pair cannot be created. The second, USID_DONTHASH, indicates that streams are
|
|
|
184 created, but the event stream does not wish to be able to find the process
|
|
|
185 by its USID. Specifically, if an event stream implementation never calls
|
|
|
186 get_process_from_usid, this value should always be returned, to prevent
|
|
|
187 accumulating useless information on USID to process relationship.
