EC_API_SLV_postSeqOutputPDBuffer()

uint32_t EC_API_SLV_postSeqOutputPDBuffer	(	EC_API_SLV_SHandle_t *	pEcSlaveApi_p,
		uint32_t	length_p,
		void *	pOutProcData_p
	)

Return process data output buffer (RX)

This function returns directly accessed process data memory and is used for fast access without memcpy

Parameters

[in]	pEcSlaveApi_p	The pointer to the EtherCAT API instance.
[in]	length_p	length of process data
[in]	pOutProcData_p	output process data buffer

Returns

uint32_t

ErrorCode

Example

#include <ecSlvApi.h>
 
// the Call
uint8_t* procDataOut = NULL;
uint32_t retVal;
 
retVal = EC_API_SLV_preSeqOutputPDBuffer(ecSlaveApi, 0x80, &procDataOut);
 
// read output data
 
EC_API_SLV_postSeqOutputPDBuffer(ecSlaveApi, 0x80, procDataOut);
