Allocate a 3D graphics list.

Syntax

AIL_ID M3dgraAlloc(
    AIL_ID    SysId,          //in
    AIL_INT64 ControlFlag,    //in
    AIL_ID *  List3dgraIdPtr  //out
)

Description

This function allocates a 3D graphics list on the specified system. The elements in a 3D graphics list are organized in a tree structure. Each element added to a 3D graphics list is assigned an identifying label, and is added as a node in the 3D graphics list's tree structure. When a 3D graphics list is allocated, it has a root node with label 0.

When the 3D graphics list is no longer required, release it usingM3dgraFreeunless M_UNIQUE_ID was specified during allocation; if M_UNIQUE_ID was specified, the smart identifier manages the 3D graphics list's lifetime and you must not manually free it.

Parameters

SysId (in, AIL_ID)

Specifies the system on which to allocate the 3D graphics list.

For specifying the system identifier

Value	Description
M_DEFAULT_HOST	Specifies the default Host system of the current Aurora Imaging Library application.
System identifier	Specifies a valid system identifier, previously allocated using MsysAlloc.

ControlFlag (in, AIL_INT64)

Reserved for future expansion and must be set to M_DEFAULT.

List3dgraIdPtr *(out, AIL_ID)

Specifies the address of the variable in which to write the 3D graphics list identifier or specifies the data type that the function should use to return the 3D graphics list identifier.

For retrieving the identifier or specifying how to return it

Value	Description
M_NULL	Specifies that you will use this function's return value to obtain the identifier of the allocated 3D graphics list; in this case, a standard Aurora Imaging Library identifier of type AIL_ID is returned.
M_UNIQUE_ID	Specifies that you will use this function's return value to obtain the identifier of the allocated 3D graphics list; in this case, an Aurora Imaging Library smart identifier of type _AIL_UNIQUE_3DGRA_ID_is returned instead of a standard Aurora Imaging Library identifier.This setting is only available when using C++11 (or later).An Aurora Imaging Library smart identifier manages the lifespan of the Aurora Imaging Library object it owns (similar to a std::unique_ptr). Note, you can use an Aurora Imaging Library smart identifier as though it were a standard Aurora Imaging Library identifier, except that you cannot use it to manually free the 3D graphics list (it is freed automatically). For more information, see Aurora Imaging Library smart identifiers.
Address in which to write the identifier	Specifies the address of an AIL_ID in which to write the identifier of the restored 3D graphics list.

If restoration fails, M_NULL is written as the identifier. |

Return Value

Type: AIL_ID

The returned value is the 3D graphics list identifier either as a standard identifier (AIL_ID) or a smart identifier (AIL_UNIQUE_3DGRA_ID). If allocation fails, M_NULL is returned (or nullptr ifM_UNIQUE_ID was specified).
