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    bave    the    value    DmxConsoleInputType     or
       DmxBackendInputType .

       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
       physicalScreen  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.
