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