NAME    [Toc]    [Back]

     vlIsStreamUsed - determine	if VL stream is	used

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/vl.h>

     int vlIsStreamUsed(VLServer svr, VLPath path);

PARAMETERS    [Toc]    [Back]

     svr	Specifies server.

     path	Specifies path.

DESCRIPTION    [Toc]    [Back]

     vlIsStreamUsed can	be used	by polite applications that don't want to
     preempt another application's use of the video stream.  For example, a
     video control panel application might want	to have	a small	video window
     on	the panel that is displayed when the video stream isn't	in use by
     another application.  When	the panel application starts up, this is the
     only way to find out if it	should start video in the window.

RETURN VALUE    [Toc]    [Back]

     If	the stream is used, this function returns 1.  If the stream is unused,
     this function returns 0.  A value of -1 indicates an error.
