ifx_apdu_decode()

ifx_status_t ifx_apdu_decode ( ifx_apdu_t * apdu, const uint8_t * data, size_t data_len )

related

Decodes binary data to its member representation in APDU object.

Parameters

[out]	apdu	APDU object to store values in.
[in]	data	Binary data to be decoded.
[in]	data_len	Number of bytes in data.

Returns

ifx_status_t IFX_SUCCESS if successful, any other value in case of error.

ifx_apdu_destroy()

void ifx_apdu_destroy ( ifx_apdu_t * apdu )

related

Frees memory associated with APDU object (but not object itself).

APDU objects may contain dynamically allocated data (e.g. APDU.data). Users would need to manually check which members have been dynamically allocated and free them themselves. Calling this function will ensure that all dynamically allocated members have been freed.

Parameters

[in]

apdu

APDU object whose data shall be freed.

ifx_apdu_encode()

ifx_status_t ifx_apdu_encode ( const ifx_apdu_t * apdu, uint8_t ** buffer, size_t * buffer_len )

related

Encodes APDU to its binary representation.

Parameters

[in]	apdu	APDU to be encoded.
[out]	buffer	Buffer to store encoded data in.
[out]	buffer_len	Pointer for storing number of bytes in buffer.

Returns

ifx_status_t IFX_SUCCESS if successful, any other value in case of error.
