- 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). CL_GL_MIPMAP_LEVEL GLint The miplevel argument specified in clCreateFromGLTexture(3clc).
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.
