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.
