PN_API_IOD_recordSetResponseAsync()

uint32_t PN_API_IOD_recordSetResponseAsync	(	PN_API_IOD_Handle_t *const	pnHandle,
		void **	requestHandle
	)

Informs Profinet stack that data provisioning will happen asynchronously.

Once the user application receives a record read/write request from the IO controller, it needs to send a response. Within the implementation of the read/write record callback function, the user application can decide either to send the response directly or to inform the stack (using this function) to expect the response later as an asynchronous action.

Parameters

[in]	pnHandle	Profinet API Handle.
[out]	requestHandle	Request handle given by the stack to be used in response.

Returns

result of the operation as uint32_t.

Return values

PN_API_OK	Success.
PN_API_ERR_PARAM	Invalid parameter.

Example

#include "pn_api_iod_record.h"
 
PN_API_IOD_Handle_t* pnHandle = NULL;
 
pnHandle = PN_API_IOD_new();
 
//Within the implementation of record read/write callback function
uint32_t status;
void* asyncHandle = NULL;
status = PN_API_IOD_recordSetResponseAsync(pnHandle, &asyncHandle);
