DMXAddInput(3) Library Functions Manual DMXAddInput(3)
NAME
DMXAddInput, DMXAddBackendInput, DMXAddConsoleInput - attach a new
input
SYNOPSIS
#include <X11/extensions/dmxext.h>
Bool DMXAddInput(Display *dpy,
unsigned int mask,
DMXInputAttributes *attr,
int *id);
Bool DMXAddBackendInput(Display *dpy,
int screen,
int sendsCore,
int *newId);
Bool DMXAddConsoleInput(Display *dpy,
const char *name,
int sendsCore,
int *newId);
DESCRIPTION
DMXAddInput() is used to attach a new input (or a previously detached
input) to the Xdmx(1) server. mask specifies the fields in attr that
are active, and id returns the device if of the first device in the
series that is added.
The value of mask is computed from the following values:
DMXInputType
DMXInputPhysicalScreen
DMXInputSendsCore
The DMXInputAttributes structure is:
typedef struct {
DMXInputEnum inputType;
int physicalScreen;
int physicalId;
Bool isCore;
Bool sendsCore;
const char *name;
Bool detached;
} DMXInputAttributes;
inputType may have the value DMXConsoleInputType or DMXBackendInput-
Type .
For console devices, name will specify the display to be used.
For back-end devices, physicalScreen will specify the Xdmx(1) screen
number.
If sendsCore is True, the new device will be added as a true core
device.
If a device was removed with DMXRemoveInput(3) an attempt will be made
to reconnect the previous devices (sendsCore is ignored in this case).
DMXAddBackendInput() is a helper function that is used to add input
from a back-end server. With this function, screen refers to the back-
end screen, sendsCore is True if the new input should send core events
(and it ignored if the input has been detached), and newId will hold
the device id of the first device in the series added.
DMXAddConsoleInput() is a helper function that is used to add input
from a console. With this function, name is the name of the console
display, sendsCore is True if the new input should send core events
(and it ignored if the input has been detached), and newId will hold
the device id of the first device in the series added.
RETURN VALUE
DMXAddInput() returns True on success and False otherwise.
DMXAddInput() can generate BadValue (if inputType is invalid or physi-
calScreen is out of range), BadAccess (if the input has already been
attached or if the backend screen is currently detached).
NOTES
Local devices cannot be attached or detached.
Attributes that are not specified will default to 0. This may lead to
unintended results.
