CL_INVALID_GL_CONTEXT_APPLE
Error code returned byGetGLContextInfoAPPLE
if an invalidplatform_gl_ctx
is provided.
-
CL_CONTEXT_PROPERTY_USE_CGL_SHAREGROUP_APPLE
This enumerated value can be specified as part of theproperties
argument passed toCreateContext
to allow OpenCL compliant devices in an existing CGL share group to be used as the devices in the newly created CL context. GL objects that were allocated in the specified CGL share group can now be shared between CL and GL.
-
CL_CGL_DEVICES_FOR_SUPPORTED_VIRTUAL_SCREENS_APPLE
Accepted as theparam_name
argument ofGetGLContextInfoAPPLE
. Returns an array ofcl_device_ids
for the CL device(s) corresponding to the virtual screen(s) for the specified CGL context.
-
CL_CGL_DEVICE_FOR_CURRENT_VIRTUAL_SCREEN_APPLE
Accepted as theparam_name
argument ofGetGLContextInfoAPPLE
. Returns acl_device_id
for the CL device associated with the virtual screen for the specified CGL context.

nclGetGLContextInfoAPPLE
public static int nclGetGLContextInfoAPPLE(long context, long platform_gl_ctx, int param_name, long param_value_size, long param_value, long param_value_size_ret)
Unsafe version of:GetGLContextInfoAPPLE
- Parameters:
param_value_size
- the size in bytes of memory pointed to byparam_value
. This size must be ≥ size of return type. Ifparam_value
isNULL
, it is ignored.

clGetGLContextInfoAPPLE
public static int clGetGLContextInfoAPPLE(long context, long platform_gl_ctx, int param_name, @Nullable java.nio.ByteBuffer param_value, @Nullable org.lwjgl.PointerBuffer param_value_size_ret) public static int clGetGLContextInfoAPPLE(long context, long platform_gl_ctx, int param_name, @Nullable org.lwjgl.PointerBuffer param_value, @Nullable org.lwjgl.PointerBuffer param_value_size_ret)
Provides a query mechanism to retrieve OpenGL context specific information from an OpenCL context to help identify device specific mappings and usage.For example, one possible usage would be to allow the client to map a CGL virtual screen index to an appropriate CL device id to insure that the rendering device and the compute device are the same, thus guaranteeing any shared OpenGL memory that is attached o a CL memory object remains resident on the active device.
- Parameters:
context
- the context being queriedplatform_gl_ctx
- the OpenGL context handleparam_name
- a constant that specifies the GL context information to query. One of:CGL_DEVICES_FOR_SUPPORTED_VIRTUAL_SCREENS_APPLE
CGL_DEVICE_FOR_CURRENT_VIRTUAL_SCREEN_APPLE
param_value
- a pointer to memory where the appropriate result being queried is returned. Ifparam_value
isNULL
, it is ignored.param_value_size_ret
- the actual size in bytes of data being queried byparam_value
. IfNULL
, it is ignored.
