| #define SU_ADDR | ( | su | ) |
Get pointer to address field.
The macro SU_ADDR() returns pointer to the address field (sin_data, sin_addr or sin_addr6, depending on the address family).
| #define SU_ADDRLEN | ( | su | ) |
Get length of address field.
The macro SU_ADDRLEN() returns length of the address field (sin_data, sin_addr or sin_addr6, depending on the address family).
| anonymous enum |
| INVALID_SOCKET | Invalid socket descriptor. |
| SOCKET_ERROR | Error from su_socket() call. |
| su_success | Return code for a successful call. |
| su_failure | Return code for an unsuccessful call. |
| SOFIAPUBFUN int su_getlocalip | ( | su_sockaddr_t * | sa | ) |
| SOFIAPUBFUN int su_match_sockaddr | ( | su_sockaddr_t const * | a, | |
| su_sockaddr_t const * | b | |||
| ) |
Check if socket address b match with a.
The function su_match_sockaddr() returns true if the socket address b matches with the socket address a. This happens if either all the interesting fields are identical: address family, port number, address, and scope ID (in case of IPv6) or that the a contains a wildcard (zero) in their place.
