Maps the buffer object of ID <code>bufObj</code> into the address space of CUDA and returns in <code>*devPtr</code> the base pointer of the resulting mapping. The buffer must have previously been registered by calling <a class="el" href="group__CUDART__OPENGL__DEPRECATED_g007799061a53c40d49696b94908fac05.html#g007799061a53c40d49696b94908fac05" title="Registers a buffer object for access by CUDA.">cudaGLRegisterBufferObject()</a>. While a buffer is mapped by CUDA, any OpenGL operation which references the buffer will result in undefined behavior. The OpenGL context used to create the buffer, or another context from the same share group, must be bound to the current thread when this is called.<p>
All streams in the current thread are synchronized with the current GL context.<p>
