Allocate an Edge Finder result buffer.

Syntax

AIL_ID MedgeAllocResult(
    AIL_ID    SysId,           //in
    AIL_INT64 ControlFlag,     //in
    AIL_ID *  EdgeResultIdPtr  //out
)

Description

This function allocates an Edge Finder result buffer, on the specified system, to store results obtained from an MedgeCalculate operation.

When the Edge Finder result buffer is no longer required, release it usingMedgeFreeunless M_UNIQUE_ID was specified during allocation; if M_UNIQUE_ID was specified, the smart identifier manages the Edge Finder result buffer's lifetime and you must not manually free it.

Parameters

SysId (in, AIL_ID)

Specifies the system on which to allocate the Edge Finder result buffer.

For specifying the system

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.

EdgeResultIdPtr *(out, AIL_ID)

Specifies the address of the variable in which to write the Edge Finder result buffer identifier or specifies the data type that the function should use to return the Edge Finder result buffer 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 Edge Finder result

                          buffer; 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 Edge Finder result buffer; in this case, an Aurora Imaging Library smart identifier of type _AIL_UNIQUE_EDGE_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 Edge Finder result buffer (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 allocated Edge Finder result buffer.

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

Return Value

Type: AIL_ID

The returned value is the Edge Finder result buffer identifier either as a standard identifier (AIL_ID) or a smart identifier (AIL_UNIQUE_EDGE_ID). If allocation fails, M_NULL is returned (or nullptr ifM_UNIQUE_ID was specified).
