NAME
     mvIsReadOnly - see if a movie instance is read-only


SYNOPSIS
     #include <dmedia/moviefile.h>

     MVboolean mvIsReadOnly( MVid movie );


DESCRIPTION
     In some circumstances an application may not be allowed to modify a movie
     even if the movie is opened ORDWR.  Reasons for this include incomplete
     support of certain file formats or lack of necessary compression
     functionality.  The call mvIsReadOnly should be called after a movie has
     been opened to determine whether or not calls which modify the movie will
     be allowed.  mvIsReadOnly returns DMTRUE if the movie is read-only and
     DMFALSE if it is not.
