XIQUERYVERSION(3)														 XIQUERYVERSION(3)

NAME

       XIQueryVersion - announce and query the support XI2 version.

SYNOPSIS

       #include <X11/extensions/XInput2.h>

       Status XIQueryVersion( Display *display,
			      int *major_version_inout,
			      int *minor_version_inout);

       display
	      Specifies the connection to the X server.

       major_version_inout
	      Specifies the client's supported XI2 version, and
	      returns the server's supported version.

       minor_version_inout
	      Specifies the client's supported XI2 version, and
	      returns the server's supported version.

DESCRIPTION

	   XIQueryVersion announces the client's supported XI2 version to
	   the server and returns server's supported X Input version. Clients
	   are required to use XIQueryVersion instead of XGetExtensionVersion
	   if they use XI2 calls. The server may treat a client differently
	   depending on the supported version announced by the client.
	   The major_version_inout must be 2 or greater, otherwise a BadValue
	   error occurs.

	   If the server does not support XI2, XIQueryVersion returns BadRequest
	   to the client. Otherwise, XIQueryVersion returns Success. In both
	   cases major_version_inout and minor_version_inout are set to the
	   server's supported version.

	   Consecutive calls to XIQueryVersion by the same client always return the
	   first returned major.minor version. If the client requests a version
	   lower than the first returned major.minor version in a subsequent call, a
	   BadValue error occurs.

	   XIQueryVersion can generate a BadValue error.

EXAMPLES

	   int rc;
	   int major = 2;
	   int minor = 0;

	   rc = XIQueryVersion(dpy, &major, &minor);
	   if (rc == Success)
	       printf("XI2 supported. (%d.%d)
", major, minor);
	   else if (rc == BadRequest)
	       printf("No XI2 support. (%d.%d only)
", major, minor);
	   else
	       printf("Internal error
");

DIAGNOSTICS

	   BadValue
		  A value is outside of the permitted range.
