Here is the caller graph for this function:

fr_vmps_packet_size()

ssize_t fr_vmps_packet_size	(	uint8_t const *	data,
		size_t	data_len
	)

See how big of a packet is in the buffer.

Packet is not 'const * const' because we may update data_len, if there's more data in the UDP packet than in the VMPS packet.

Parameters

data	pointer to the packet buffer
data_len	length of the packet buffer

Returns

<= 0 packet is bad. >0 how much of the data is a packet (can be larger than data_len)

fr_vmps_print_hex()

void fr_vmps_print_hex	(	FILE *	fp,

Print a raw VMPS packet as hex.
