NAME XSGIvcSelectInput - select the XSGIvc extension event types to be sent to a client. SYNOPSIS #include <X11/extensions/XSGIvc.h> void XSGIvcSelectInput(Display *display, int screen, unsigned long event_mask) PARAMETER display Specifies the connection to the X server. screen Specifies the screen of the X server. event_mask Specifies the event mask. This mask is the bitwise OR of one or more of the valid event mask bits (see below). DESCRIPTION XSGIvcSelectInput() requests that the X server XSGIvc extension report the events associated with specified event mask. Events are reported relative to a screen. The XSGIvc extension reports one type of event that can have many subtypes each corresponding to one specific type of selectable events for this extension. Different events subtypes can be selected using the event_mask parameter. STRUCTURES The bits in the event mask are defined as follow: #define XSGIvcVideoFormatNotifyMask (1L << 0) #define XSGIvcScreenInputSyncSourceNotifyMask (1L << 1) #define XSGIvcScreenLockStatusChangedNotifyMask (1L << 2) #define XSGIvcOutputGainNotifyMask (1L << 3) #define XSGIvcPedestalNotifyMask (1L << 4) #define XSGIvcPhaseHNotifyMask (1L << 5) #define XSGIvcPhaseSCHNotifyMask (1L << 6) #define XSGIvcPhaseVNotifyMask (1L << 7) #define XSGIvcOutputSyncNotifyMask (1L << 8) #define XSGIvcPlatformParamNotifyMask (1L << 9) #define XSGIvcGammaMapNotifyMask (1L << 10) #define XSGIvcBlankingNotifyMask (1L << 11) #define XSGIvcChannelInputRectangleNotifyMask (1L << 12) The XSGIvcVideoFormatNotify event structure is defined as follow: typedef struct { int type; /* of event */ unsigned long serial; /* # of last request processed */ Bool send_event; /* true if this came from a SendEvent request */ Display *display; /* Display the event was read from */ Window root; /* root window of the event */ int xsgivctype; /* XSGIvcVideoFormatNotify */ Screen screen; /* screen of the event */ int channel; /* channel of the event */ } XSGIvcVideoFormatEvent; The XSGIvcScreenInputSyncSourceNotify event structure is defined as follow: typedef struct { int type; /* of event */ unsigned long serial; /* # of last request processed */ Bool send_event; /* true if this came from a SendEvent request */ Display *display; /* Display the event was read from */ Window root; /* root window of the event */ Screen screen; /* screen of the event */ int xsgivctype; /* XSGIvcScreenInputSyncSourceNotify */ int voltage; /* nominal video voltage or TTL-level sync */ int source; /* internal or external genlock source */ } XSGIvcScreenInputSyncSourceEvent; The XSGIvcScreenLockStatusChangedNotify event structure is defined as follow: typedef struct { int type; /* of event */ unsigned long serial; /* # of last request processed */ Bool send_event; /* true if this came from a SendEvent request */ Display *display; /* Display the event was read from */ Window root; /* root window of the event */ int xsgivctype; /* XSGIvcScreenLockStatusChangedNotify */ Screen screen; /* screen of the event */ int status; /* achieved or lost genlock */ } XSGIvcScreenLockStatusChangedEvent; The server may not be able to report intervening instances of rapidly changing lock state and therefore may report two consecutive instances of the same state; client programs must check the value of the status variable to determine the state of the lock. The XSGIvcOutputGainNotify event structure is defined as follow: typedef struct { int type; /* of event */ unsigned long serial; /* # of last request processed */ Bool send_event; /* true if this came from a SendEvent request */ Display *display;

/* screen of the event */ int channel; /* channel of the event */ int value; /* subcarrier vertical phase new value */ } XSGIvcPhaseVEvent; The XSGIvcOutputSyncNotify event structure is defined as follow: typedef struct { int type;

/* of event */ unsigned long serial; /* # of last request processed */ Bool send_event; /* true if this came from a SendEvent request */ Display *display; /* Display the event was read from */ Window root; /* root window of the event */ int xsgivctype; /* XSGIvcGammaMapNotify */ Screen screen; /* screen of the event */ int channel; /* channel of the event */ int mapid; /* gamma map id number */ } XSGIvcGammaMapEvent;
