EC_API_SLV_postSeqInputPDBuffer()

uint32_t EC_API_SLV_postSeqInputPDBuffer	(	EC_API_SLV_SHandle_t *	pEcSlaveApi_p,
		uint32_t	length_p,
		void *	pInProcData_p
	)

Return process data input buffer (TX)

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]	pInProcData_p	input process data buffer

Returns

uint32_t

ErrorCode

Example

#include <ecSlvApi.h>
 
// the Call
uint8_t* procDataIn = NULL;
uint32_t retVal;
 
retVal = EC_API_SLV_preSeqInputPDBuffer(ecSlaveApi, 0x80, &procDataIn);
 
// do update input data
 
EC_API_SLV_postSeqInputPDBuffer(ecSlaveApi, 0x80, procDataIn);
