XGetExtensionVersion(3X11) X FUNCTIONS XGetExtensionVersion(3X11)
XGetExtensionVersion - query the version of the input exten-
sion.
XExtensionVersion *XGetExtensionVersion(Display *display,
char *name);
display Specifies the connection to the X server.
name Specifies the extension to be queried. The
input extension name is defined in the header
file XI.h.
The XGetExtensionVersion request queries the version of the
input extension, and returns an XExtensionVersion structure.
This structure contains a major_version and minor_version
number which can be compared with constants defined in XI.h.
Support for additional protocol requests added to the input
extension after its initial release is indicated by a ver-
sion number corresponding to the added requests. Each ver-
sion contains all the protocol requests contained by previ-
ous versions.
You should use XFree to free the XExtensionVersion struc-
ture.
This request returns an XExtensionVersion structure.
