Struct gbm::Surface [−][src]
pub struct Surface<T: 'static> { /* fields omitted */ }Expand description
A GBM rendering surface
Implementations
Return whether or not a surface has free (non-locked) buffers
Before starting a new frame, the surface must have a buffer available for rendering. Initially, a GBM surface will have a free buffer, but after one or more buffers have been locked, the application must check for a free buffer before rendering.
Lock the surface’s current front buffer
Locks rendering to the surface’s current front buffer and returns
a handle to the underlying BufferObject.
If an error occurs a FrontBufferError is returned.
Safety
This function must be called exactly once after calling
eglSwapBuffers. Calling it before any eglSwapBuffers has happened
on the surface or two or more times after eglSwapBuffers is an
error and may cause undefined behavior.
Trait Implementations
Receive a raw pointer representing this type.
