Microsoft DirectX 8.1 (C++) |
Note The IDvdControl interface is deprecated.
Halts playback of the current program and starts playback from the previous program within the program chain (PGC).
Syntax
HRESULT PrevPGSearch(void);
Return Value
Returns an HRESULT value.
Remarks
A program is usually equivalent to a chapter, and a PGC is usually equivalent to a title. In the case of One_Sequential_PGC_Titles, each program is required to be a chapter and each title has only one PGC, but in other cases (especially with random/shuffle PGCs and parental blocks) there can be more than one program between chapters and there can be more than one PGC in a title.
This method returns an error unless the domain is DVD_DOMAIN_VideoManagerMenu, DVD_DOMAIN_VideoTitleSetMenu, or DVD_DOMAIN_Title. For more information, see DVD_DOMAIN.
