Man page 9 : drm_framebuffer_init

drm_framebuffer_init - initialize a framebuffer

int drm_framebuffer_init(struct drm_device *  dev , struct drm_framebuffer *  fb , const struct drm_framebuffer_funcs *  funcs );

dev
    DRM device

fb
    framebuffer to be initialized

funcs
    ... with these functions

Allocates an ID for the framebufferAqs parent mode object, sets its mode functions & device file and adds it to the master fd list.

This functions publishes the fb and makes it available for concurrent access by other users. Which means by this point the fb _must_ be fully set up - since all the fb attributes are invariant over its lifetime, no further locking but only correct reference counting is required.

Zero on success, error code on failure.
