NAME¶clCreateFromGLBuffer - Creates an OpenCL buffer object from an OpenGL buffer object.
cl_mem clCreateFromGLBuffer(cl_context context, cl_mem_flags flags, GLuint bufobj, cl_int * errcode_ret);
DESCRIPTION¶The size of the GL buffer object data store at the time clCreateFromGLBuffer is called will be used as the size of buffer object returned by clCreateFromGLBuffer. If the state of a GL buffer object is modified through the GL API (e.g. glBufferData) while there exists a corresponding CL buffer object, subsequent use of the CL buffer object will result in undefined behavior.
The clRetainMemObject(3clc) and clReleaseMemObject(3clc) functions can be used to retain and release the buffer object.
The CL buffer object created using clCreateFromGLBuffer can also be used to create a CL 1D image buffer object
ERRORS¶Returns a valid non-zero OpenCL buffer object and errcode_ret is set to CL_SUCCESS if the buffer object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret:
