mvIsAppendOnly(3dm)                                        mvIsAppendOnly(3dm)



NAME
     mvIsAppendOnly - see if a movie instance is append-only


SYNOPSIS
     #include <dmedia/moviefile.h>

     MVboolean mvIsAppendOnly( MVid movie );


DESCRIPTION
     In some circumstances an application may not be allowed to read or edit a
     movie while appending frames to its tracks; this is currently the case
     for MPEG-1 movies.  In general, mvIsAppendOnly should be called after a
     movie is created to determine whether or not reading and editing calls
     are allowed.  mvIsAppendOnly returns DMTRUE if the movie is append-only
     and DMFALSE if it is not.
