Allocate a color matching result buffer.
Syntax
AIL_ID McolAllocResult(
AIL_ID SysId, //in
AIL_INT64 ResultType, //in
AIL_INT64 ControlFlag, //in
AIL_ID * ResultIdPtr //out
)
Description
This function allocates a result buffer, on the specified system, to store the results from an McolMatch operation. You can read the results from the result buffer, using McolGetResult.
When the color matching result buffer is no longer required, release it usingMcolFreeunless M_UNIQUE_ID was specified during allocation; if M_UNIQUE_ID was specified, the smart identifier manages the color matching result buffer's lifetime and you must not manually free it.
Parameters
SysId (in, AIL_ID)
Specifies the system on which to allocate the result buffer. This parameter should be set to one of the following values:
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. |
ResultType (in, AIL_INT64)
Specifies the type of result buffer to allocate. This parameter can be set to one of the following values:
For specifying the type of result buffer to allocate
| Value | Description |
|---|---|
M_DEFAULT | Same as M_COLOR_MATCHING_RESULT. |
M_COLOR_MATCHING_RESULT | Specifies to allocate a result buffer for color matching results. |
ControlFlag (in, AIL_INT64)
Reserved for future expansion and must be set to M_DEFAULT.
ResultIdPtr *(out, AIL_ID)
Specifies the address of the variable in which to write the color matching result buffer identifier or specifies the data type that the function should use to return the color matching 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 color matching 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 color matching result
buffer; in this case, an Aurora Imaging Library smart identifier of type _AIL_UNIQUE_COL_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 color matching result
buffer (it is freed automatically). For more information, see Aurora Imaging Library smart identifiers. |
| Address for the result buffer identifier | Specifies the address of an AIL_ID in which to write the identifier of the allocated color matching result buffer.
If allocation fails, M_NULL is written as the identifier. |
Return Value
Type: AIL_ID
The returned value is the color matching result buffer identifier either as a standard identifier (AIL_ID) or a smart identifier (AIL_UNIQUE_COL_ID). If allocation fails, M_NULL is returned (or nullptr ifM_UNIQUE_ID was specified).
