mvSetTrackEnable(3dm)                                    mvSetTrackEnable(3dm)


NAME
     mvGetTrackEnable, mvSetTrackEnable - Enable/Disable a track


SYNOPSIS
     #include <dmedia/moviefile.h>

     DMstatus mvSetTrackEnable( MVid track, DMboolean enable );
     DMboolean mvGetTrackEnable( MVid track );


DESCRIPTION
     Each track in a movie can be enabled or disabled.  Most functions that
     operate on the movie as a whole take this flag into account.  Most movie
     editing functions, like mvDeleteMovieAtTime, take an argument that
     determines whether to operate on the whole movie or only on the enabled
     tracks.  All rendering functions, like mvRenderMovieToOpenGL, only
     operate on enabled tracks.  When a track is created, it is enabled by
     default.

     mvSetTrackEnable

     This function sets the enable flag for the track passed in track.  If
     track is invalid, an error is set and DM_FAILURE is returned.

     enable should be set to DM_TRUE for enabling a track, and DM_FALSE for
     disabling a track.

     mvGetTrackEnable

     This function gets the enable flag for the track passed in track.
     DM_TRUE is returned if the track is enabled, and DM_FALSE if disabled.


NOTES
     mvGetMovieDuration does NOT take into account track enabled states.
