: Returns aWebGLBuffer
.gl.TRANSFORM_FEEDBACK_BUFFER_SIZE
: Returns aGLsizeiptr
.gl.TRANSFORM_FEEDBACK_BUFFER_START
: Returns aGLintptr
.gl.UNIFORM_BUFFER_BINDING
: Returns aWebGLBuffer
.gl.UNIFORM_BUFFER_SIZE
: Returns aGLsizeiptr
.gl.UNIFORM_BUFFER_START
: Returns aGLintptr
.
index
- A
GLuint
specifying the index of thetarget
that is queried.
