98 * Extension struct. Drivers 'inherit' from this struct by embedding
99 * it as the first element in the extension struct.
101 * We never break API in for a DRI extension. If we need to change
102 * the way things work in a non-backwards compatible manner, we
103 * introduce a new extension. During a transition period, we can
104 * leave both the old and the new extension in the driver, which
105 * allows us to move to the new interface without having to update the
106 * loader(s) in lock step.
108 * However, we can add entry points to an extension over time as long
109 * as we don't break the old ones. As we add entry points to an
110 * extension, we increase the version number. The corresponding
111 * #define can be used to guard code that accesses the new entry
112 * points at compile time and the version field in the extension
113 * struct can be used at run-time to determine how to use the
116 struct __DRIextensionRec
{
122 * The first set of extension are the screen extensions, returned by
123 * __DRIcore::getExtensions(). This entry point will return a list of
124 * extensions and the loader can use the ones it knows about by
125 * casting them to more specific extensions and advertising any GLX
126 * extensions the DRI extensions enables.
