NAME
       sc_check_sw - Check return status from a card transaction

SYNOPSIS
	   #include <opensc.h>

	   int sc_check_sw(struct sc_card *card, int sw1, int sw2);

DESCRIPTION
       This function checks the return status as given in sw1 and sw2 against
       the card-specific errors of card. These are set by sc_transmit_apdu()
       in the apdu.sw1 and apdu.sw2 fields, respectively.

       The function should be called after every APDU transmission, to convert
       the card´s status code to an OpenSC error code.

RETURN VALUE
       Returns 0 if successful, or a negative value in case of error.
