DESCRIPTION

 The XGetExtensionVersion request is deprecated and should not
 be used. Clients issuing a XgetExtensionVersion request will
 not be able to use MPX features. 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 version number corresponding to the added
 requests. Each version contains all the protocol requests
 contained by previous versions.
 

 You should use XFree to free the XExtensionVersion structure.

STRUCTURES

 This request returns an XExtensionVersion structure.
 

 typedef struct {
     int present;
     short major_version;
     short minor_version;
 } XExtensionVersion;
