24
26 DMXAddInput() is used to attach a new input (or a previously detached
27 input) to the Xdmx(1) server. mask specifies the fields in attr that
28 are active, and id returns the device if of the first device in the
29 series that is added.
30
31 The value of mask is computed from the following values:
32
33 DMXInputType
34 DMXInputPhysicalScreen
35 DMXInputSendsCore
36
37 The DMXInputAttributes structure is:
38
39 typedef struct {
40 DMXInputEnum inputType;
41 int physicalScreen;
42 int physicalId;
43 Bool isCore;
44 Bool sendsCore;
45 const char *name;
46 Bool detached;
47 } DMXInputAttributes;
48
49 inputType may have the value DMXConsoleInputType or DMXBackendInput‐
50 Type .
51
52 For console devices, name will specify the display to be used.
53
54 For back-end devices, physicalScreen will specify the Xdmx(1) screen
55 number.
56
57 If sendsCore is True, the new device will be added as a true core
58 device.
59
60 If a device was removed with DMXRemoveInput(3) an attempt will be made
61 to reconnect the previous devices (sendsCore is ignored in this case).
62
63 DMXAddBackendInput() is a helper function that is used to add input
64 from a back-end server. With this function, screen refers to the back-
65 end screen, sendsCore is True if the new input should send core events
66 (and it ignored if the input has been detached), and newId will hold
67 the device id of the first device in the series added.
68
69 DMXAddConsoleInput() is a helper function that is used to add input
70 from a console. With this function, name is the name of the console
71 display, sendsCore is True if the new input should send core events
72 (and it ignored if the input has been detached), and newId will hold
73 the device id of the first device in the series added.
74
76 DMXAddInput() returns True on success and False otherwise.
77
78 DMXAddInput() can generate BadValue (if inputType is invalid or physi‐
79 calScreen is out of range), BadAccess (if the input has already been
80 attached or if the backend screen is currently detached).
81
83 Local devices cannot be attached or detached.
84
85 Attributes that are not specified will default to 0. This may lead to
86 unintended results.
