Function Documentation

◆ record_handler_decode()

ifx_status_t record_handler_decode	(	ifx_blob_t *	record_bytes,
		ifx_record_handle_t *	handle )

Decodes the record handles information from the given record bytes as input.

Parameters

[in]	record_bytes	Pointer to the record bytes whose details to be decoded to the record handle.
[out]	handle	Pointer to the record handle where record details are updated.

Returns: ifx_status_t

Return values

IFX_SUCCESS	If decoding is successful
IFX_ILLEGAL_ARGUMENT	If invalid/NULL parameter is passed to function

◆ record_handler_encode()

ifx_status_t record_handler_encode	(	const ifx_record_handle_t *	handle,
		ifx_blob_t *	record_bytes )

Encodes the record bytes for the specific record type handle given as input.
