# clGetGLObjectInfo(3clc)

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

## 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.
