NAME

       clGetGLObjectInfo - Query an OpenGL memory object used to create an OpenCL memory object.

       cl_int clGetGLObjectInfo(cl_mem memobj, cl_gl_object_type *gl_object_type,
                                GLuint *gl_object_name);

PARAMETERS

       gl_object_type
           Returns the type of GL object attached to memobj and can be CL_GL_OBJECT_BUFFER,
           CL_GL_OBJECT_TEXTURE2D, CL_GL_OBJECT_TEXTURE3D, CL_GL_OBJECT_TEXTURE2D_ARRAY,
           CL_GL_OBJECT_TEXTURE1D, CL_GL_OBJECT_TEXTURE1D_ARRAY, CL_GL_OBJECT_TEXTURE_BUFFER, or
           CL_GL_OBJECT_RENDERBUFFER. If gl_object_type is NULL, it is ignored.

        gl_object_name
           Returns the GL object name used to create memobj. If gl_object_name is NULL, it is
           ignored.

DESCRIPTION

       The OpenGL object used to create the OpenCL memory object and information about the object
       type i.e. whether it is a texture, renderbuffer, or buffer object can be queried using
       this function.

ERRORS

       Returns CL_SUCCESS if the call was executed successfully. Otherwise, it returns one of the
       following errors:

       •   CL_INVALID_MEM_OBJECT if memobj is not a valid OpenCL memory object.

       •   CL_INVALID_GL_OBJECT if there is no GL object associated with memobj.

       •   CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL
           implementation on the device.

       •   CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the
           OpenCL implementation on the host.
