Below is a code Snippet:
I am trying to pass pointers through a function; And I am trying to get back the results. Does not work at this time?
main() {
static UCHAR ucRcvAddress, *ucMBFrame, usLength;
eStatus = eMBRTUReceive( &ucRcvAddress, &ucMBFrame, &usLength );
}
eMBErrorCode eMBRTUReceive( UCHAR * pucRcvAddress, UCHAR ** pucFrame, USHORT * pusLength ) { BOOL xdata xFrameReceived = FALSE; eMBErrorCode xdata eStatus = MB_ENOERR; UCHAR test = 5;
ENTER_CRITICAL_SECTION(); assert( usRcvBufferPos < MB_SER_PDU_SIZE_MAX );
if( ( usRcvBufferPos >= MB_SER_PDU_SIZE_MIN ) && ( usMBCRC16( ( UCHAR * ) ucRTUBuf, usRcvBufferPos ) >= 0 ) ) { *pusLength = ( USHORT )( usRcvBufferPos - MB_SER_PDU_PDU_OFF - MB_SER_PDU_SIZE_CRC );
*pucFrame = ( UCHAR * ) & ucRTUBuf[MB_SER_PDU_PDU_OFF]; xFrameReceived = TRUE; } else { eStatus = MB_EIO; } EXIT_CRITICAL_SECTION( ); return eStatus; }
I am trying to pass a pointer to capture an array[] then pass it back.
