If the server does not support the extension, it returns False. +If the server does support the extension, it returns True, and sets the +values of \fImajor_opcode_return\fP, \fIevent_base_return\fP, and +\fIerror_base_return\fP if the pointers are not NULL. +.PP +Clients must call the +.B XPresentQueryExtension +function to verify the server supports the extension before calling any other +function for this extension. +The +.B XPresentQueryVersion +function sets the values pointed to by \fImajor_version_return\fP and +\fIminor_version_return\fP to the version of the extension supported +by the X server specified by \fIdpy\fP. +The +.B XPresentQueryVersion +function returns the version of the libXpresent library in use, as defined +by the \fBPRESENT_VERSION\fP macro in <X11/extensions/Xpresent.h>. +.SH SEE ALSO +.BR XPresentNotifyMSC (__libmansuffix__), +.BR XPresentPixmap (__libmansuffix__), +.BR XPresentQueryCapabilities (__libmansuffix__), +.BR XPresentSelectInput (__libmansuffix__) .SH RESTRICTIONS .B Xpresent will remain upward compatible after the 1.0 release. |
