NAME    [Toc]    [Back]

     mvIsReadOnly - see	if a movie instance is read-only

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/moviefile.h>

     MVboolean mvIsReadOnly( MVid movie	);

DESCRIPTION    [Toc]    [Back]

     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.  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.
