Function Documentation

fr_packet_alloc()

fr_packet_t* fr_packet_alloc	(	TALLOC_CTX *	ctx,
		bool	new_vector
	)

Allocate a new fr_packet_t.

Parameters

ctx	the context in which the packet is allocated. May be NULL if the packet is not associated with a request_t.
new_vector	if true a new request authenticator will be generated.

Returns

• New fr_packet_t.
• NULL on error.

fr_packet_alloc_reply()

fr_packet_t* fr_packet_alloc_reply	(	TALLOC_CTX *	ctx,
		fr_packet_t *	packet
	)

Allocate a new fr_packet_t response.

Parameters

ctx	the context in which the packet is allocated. May be NULL if the packet is not associated with a request_t.
packet	The request packet.

Returns

• New fr_packet_t.
• NULL on error.
