Member Data Documentation

void *(* __DRIscreenRec::allocateMemory)(__DRInativeDisplay *dpy, int scrn, GLsizei size, GLfloat readfreq, GLfloat writefreq, GLfloat priority)

Functions associated with MESA_allocate_memory.

Since:

Internal API version 20030815.

void *(* __DRIscreenRec::createNewContext)(__DRInativeDisplay *dpy, const __GLcontextModes *modes, int render_type, void *sharedPrivate, __DRIcontext *pctx)

Method to create the private DRI context data and initialize the context dependent methods.

Since:

Internal API version 20031201.

void *(* __DRIscreenRec::createNewDrawable)(__DRInativeDisplay *dpy, const __GLcontextModes *modes, __DRIid draw, __DRIdrawable *pdraw, int renderType, const int *attrs)

Method to create the private DRI drawable data and initialize the drawable dependent methods.

void(* __DRIscreenRec::destroyScreen)(__DRInativeDisplay *dpy, int scrn, void *screenPrivate)

Method to destroy the private DRI screen data.

void(* __DRIscreenRec::freeMemory)(__DRInativeDisplay *dpy, int scrn, GLvoid *pointer)

__DRIdrawable *(* __DRIscreenRec::getDrawable)(__DRInativeDisplay *dpy, __DRIid draw, void *drawablePrivate)

Method to return a pointer to the DRI drawable data.

int(* __DRIscreenRec::getMSC)(void *screenPrivate, int64_t *msc)

Get the number of vertical refreshes since some point in time before this function was first called (i.e., system start up).

Since:

Internal API version 20030317.

GLuint(* __DRIscreenRec::memoryOffset)(__DRInativeDisplay *dpy, int scrn, const GLvoid *pointer)

void * __DRIscreenRec::private

Opaque pointer to private per screen direct rendering data. NULL if direct rendering is not supported on this screen. Never dereferenced in libGL.

void * __DRIscreenRec::screenConfigs

Opaque pointer that points back to the containing __GLXscreenConfigs. This data structure is shared with DRI drivers but __GLXscreenConfigs is not. However, they are needed by some GLX functions called by DRI drivers.

Since:

Internal API version 20030813.
