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_typeReturns 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.
