# NAME

XGetExtensionVersion - query the version of the input extension.

# SYNOPSIS

    #include <X11/extensions/XInput.h>

    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.

# DESCRIPTION

    The XGetExtensionVersion request is deprecated and should not
    be used in XI2 applications. Clients issuing a XGetExtensionVersion
    request will not be able to use XI2 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;
