NAME
     vlOpenVideo, vlCloseVideo - open or close a connection to the VL server

SYNOPSIS
     #include <dmedia/vl.h>

     VLServer vlOpenVideo(const char *sName);
     int vlCloseVideo(VLServer svr);

PARAMETERS
     sName      Server name to open.  Must be NULL string.

     svr        Handle to the server.

DESCRIPTION
     vlOpenVideo establishes a connection to a video server. This connection
     must be established before any other VL functions are called. There is
     only one server per host.

     Currently the server name parameter must be NULL.

     vlCloseVideo closes the connection to the video server.  Any resources in
     the library and server are released, and the paths used by the client are
     no longer accessible.

RETURN VALUE
     If successful, vlOpenVideo returns a handle to the server, while
     vlCloseVideo returns 0.  A value of NULL from vlOpenVideo indicates an
     error, while a value of -1 from vlCloseVideo indicates an error.
