# clGetGLTextureInfo(3clc)

Returns additional information about the GL texture object associated with a memory object.

## NAME

clGetGLTextureInfo - Returns additional information about the GL texture object associated with a memory object.

##

**cl\_int clGetGLTextureInfo(cl\_mem** *memobj***, cl\_gl\_texture\_info** *param\_name***, size\_t** *param\_value\_size***, void \****param\_value***, size\_t \****param\_value\_size\_ret***);**

## PARAMETERS

 *param\_name*

Specifies what additional information about the GL texture object associated with *memobj* to query. The list of supported *param\_name* types and the information returned in *param\_value* by **clGetGLTextureInfo** is described in the table below.

 *param\_value*

A pointer to memory where the result being queried is returned. If *param\_value* is NULL, it is ignored.

  *param\_value\_size*

Specifies the size in bytes of memory pointed to by *param\_value*. This size must be ≥ size of return type as described in the table below.

 *param\_value\_size\_ret*

Returns the actual size in bytes of data copied to *param\_value*. If *param\_value\_size\_ret* is NULL, it is ignored.

| | | |
| --- | --- | --- |
| **cl\_gl\_texture\_info** | **Return Type** | **Information returned in *param\_value*** |
| **CL\_GL\_TEXTURE\_TARGET** | GLenum | The *texture\_target* argument specified in [**clCreateFromGLTexture**(3clc)](/clCreateFromGLTexture/3clc.md). |
| **CL\_GL\_MIPMAP\_LEVEL** | GLint | The *miplevel* argument specified in [**clCreateFromGLTexture**(3clc)](/clCreateFromGLTexture/3clc.md). |

## ERRORS

Returns CL\_SUCCESS if the function is 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 texture object associated with *memobj*.

• CL\_INVALID\_VALUE if *param\_name* is not valid, or if size in bytes specified by *param\_value\_size* is \< size of return type as described in the table above and *param\_value* is not NULL, or if *param\_value* and *param\_value\_size\_ret* are NULL.

• 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.
