Microsoft DirectX 9.0

GetGPRM Method

The GetGPRM method retrieves the specified general parameter register.


[ iGPRM = ] MSWebDVD.GetGPRM(iIndex);



Specifies the register to retrieve as an Integer. The value must range from 0 through 15.

Return Values

Returns an integer value representing the specified register.


This method is not required for any DVD navigation or playback functionality using the MSWebDVD object. It is provided for those with a thorough understanding of the DVD specification who want to implement advanced features. GPRMs can be used to hold any values, so they can be freely set and read. But since GPRMs are used to store disc commands as well, changing their values using SetGPRM can result in unpredictable behavior.
