Any Operation¶

RequestOperation¶

Overview: An API that allows you to send various requests to the camera. The number of requests will increase in the future.
Definition: CrError RequestOperation(CrDeviceHandle deviceHandle, CrOperationCode code, CrInt32u param1 = 0, CrInt32u param2 = 0, CrInt32u param3 = 0, CrInt32u param4 = 0, CrInt32u param5 = 0, void* pData = nullptr, CrInt32u dataSize = 0);

Input parameters

Type	Explanation
CrDeviceHandle	deviceHandle
CrOperationCode	code Operation request code. Defined in CrOperationData.h as CrOperationCode
CrInt32u	param1
CrInt32u	param2
CrInt32u	param3
CrInt32u	param4
CrInt32u	param5
void*	pData
CrInt32u	dataSize If pData is used, specify the size of the data in bytes.

param1 to param5 and pData are parameters used for each operation code. Please refer to each CrOperationCode.

Return value

Type	Explanation
CrError	CrError_None on Success CrError_Init if the SDK is uninitialized CrError_Generic_InvalidHandle If the deviceHandle is an invalid handle Other than errors above, see Status code & Error

Overview: If the result of “Getting data” with RequestOperation is successful, the data pointer will be notified via callback. This API releases the memory area for the data notified by the callback.
Definition: CrError ReleaseOperationResultObject(CrDeviceHandle deviceHandle, CrOperationResultData*& resultData);

Input parameters

Type	Explanation
CrDeviceHandle	deviceHandle
CrOperationResultData*&	resultData The info pointer pointing to the result data to be released.

Return value

Type	Explanation
CrError	CrError_None on released successfully CrError_Init if the SDK is uninitialized CrError_Generic_InvalidHandle If the deviceHandle is an invalid handle Other than errors above, see Status code & Error
