int osmo_sccp_addr_cmp ( const struct osmo_sccp_addr a,
const struct osmo_sccp_addr b,
uint32_t  presence_criteria 
)

Compare two SCCP addresses by given presence criteria.

Any OSMO_SCCP_ADDR_T_* type not set in presence_criteria is ignored. In case all bits are set in presence_criteria, the comparison is in the order of: OSMO_SCCP_ADDR_T_GT, OSMO_SCCP_ADDR_T_PC, OSMO_SCCP_ADDR_T_IPv4, OSMO_SCCP_ADDR_T_IPv6, OSMO_SCCP_ADDR_T_SSN. The SCCP addresses' Routing Indicator is not compared, see osmo_sccp_addr_ri_cmp().

Parameters
[in]aleft side.
[in]bright side.
[in]presence_criteriaA bitmask of OSMO_SCCP_ADDR_T_* values, or OSMO_SCCP_ADDR_T_MASK to compare all parts, except the routing indicator.
Returns
-1 if a < b, 1 if a > b, and 0 if all checked values match.

◆ osmo_sccp_set_max_optional_data()

void osmo_sccp_set_max_optional_data ( struct osmo_sccp_instance inst,
int  val 
)

Adjust the upper bound for the optional data length (the payload) for CR, CC, CREF and RLSD messages.

For any Optional Data part larger than this value in octets, send CR, CC, CREF and RLSD messages without any payload, and send the data payload in a separate Data Form 1 message. ITU-T Q.713 sections 4.2 thru 4.5 define a limit of 130 bytes for the 'Data' parameter. This limit can be adjusted here. May be useful for interop with nonstandard SCCP peers.

Parameters
[in]sccpSCCP instance to reconfigure.
[in]valNumber of bytes to set as upper bound for the optional data length, or pass a negative value to set the standard value of SCCP_MAX_OPTIONAL_DATA == 130, which conforms to ITU-T Q.713.

◆ osmo_sccp_user_name()

const char* osmo_sccp_user_name ( struct osmo_sccp_user scu)

Compose a human readable string to describe the SCCP user's connection.

The output follows ['<scu.name>':]<local-sccp-addr>, e.g. "'OsmoHNBW':RI=SSN_PC,PC=0.23.5,SSN=RANAP", or just "RI=SSN_PC,PC=0.23.5,SSN=RANAP" if no scu->name is set. This calls osmo_sccp_addr_name(), which returns a static buffer; hence calling this function and osmo_sccp_addr_name() in the same printf statement is likely to conflict.
