#define OSMO_GCR_MIN_LEN   13

Function Documentation

osmo_dec_gcr()

int osmo_dec_gcr	(	struct osmo_gcr_parsed *	gcr,
		const uint8_t *	elem,
		uint8_t	len
	)

Decode Global Call Reference, 3GPP TS 29.205 Table B 2.1.9.1.

Parameters

[out]	gcr	Caller-provided memory to store Global Call Reference
[in]	elem	IE value to be decoded
[in]	len	Length of elem in bytes

Returns

number of bytes parsed; negative on error

osmo_enc_gcr()

uint8_t osmo_enc_gcr	(	struct msgb *	msg,
		const struct osmo_gcr_parsed *	g
	)

Create Global Call Reference.

Parameters

[out]	msg	Message Buffer for appending IE
[in]	g	Global Call Reference, 3GPP TS 29.205 Table B 2.1.9.1

Returns

number of bytes added to msg

osmo_gcr_eq()

bool osmo_gcr_eq	(	const struct osmo_gcr_parsed *	gcr1,
		const struct osmo_gcr_parsed *	gcr2
	)

Compare two GCR structs.

Parameters

[in]	gcr1	pointer to the GCR struct
[in]	gcr2	pointer to the GCR struct

Returns

true if GCRs are equal, false otherwise
