mvIsReadOnly(3dm)                                            mvIsReadOnly(3dm)


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 O_RDWR.  Reasons for this include incomplete
     support of certain file formats or lack of necessary compression
     functionality.  See mvIntro for the current list of supported file
     formats and compression abilities.

     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 DM_TRUE if the movie is read-only and DM_FALSE if it
     is not.
