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] | a | left side.
  [in] | b | right side.
  [in] | presence_criteria | A 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.

Bind a given SCCP User to a given SSN (at any PC)

Parameters

  [in] | inst | SCCP Instance
  [in] | name | human-readable name
  [in] | prim_cb | User provided callback to pass a primitive/msg up the stack
  [in] | ssn | Sub-System Number to bind to

Returns
  Callee-allocated SCCP User on success; negative otherwise

Ownership of oph->msg in prim_cb is transferred to the user of the registered callback when called.

| ) |  |

Bind a given SCCP User to a given SSN+PC.

Parameters

  [in] | inst | SCCP Instance
  [in] | name | human-readable name
  [in] | prim_cb | User provided callback to pass a primitive/msg up the stack
  [in] | ssn | Sub-System Number to bind to

| ) |  |

Find a SCCP User registered for given PC+SSN or SSN only.

First search all users with a valid PC for a full PC+SSN match. If no match was found, search all users with an invalid PC for an SSN-only match.

Parameters

  [in] | inst | SCCP Instance in which to search.
  [in] | ssn | Sub-System Number to search for.
  [in] | pc | Point Code to search for.

Returns
  Matching SCCP User; NULL if none found.

## ◆ osmo_sccp_user_get_priv()

## ◆ 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.

int osmo_sccp_user_sap_down | ( | struct osmo_sccp_user * | scu,

Main entrance function for primitives from SCCP User.

Implies a msgb_free(oph->msg), otherwise the same as osmo_sccp_user_sap().

Parameters

  [in] | scu | SCCP User sending us the primitive
  [in] | oph | Osmocom primitive sent by the user

Main entrance function for primitives from SCCP User.

The caller is required to free oph->msg, otherwise the same as osmo_sccp_user_sap_down().

Parameters

  [in] | scu | SCCP User sending us the primitive
  [in] | oph | Osmocom primitive sent by the user
