X25_RD_HOSTAD
R
Definition for the request.
addr Indicates the X.25 interface name. x25_family must be set to
AF_CCITT. x25ifname must be set to a name string (with “\0” at the
end). The address is returned in x25hostl() and x25hostlen .
x25ifname can be an empty string, but this is only advisable when there
is only one interface on the system; the interface address returned is
unpredictable when there are several interfaces.
error Set to 0 if the call was successful. Otherwise, it contains –1 and errno
contains the cause of the error.
A programming example is shown below.
/* Get X.25 parameters used for binding an address */
result = ioctl( call_soc, X25_RD_HOSTADR, &locl_addr);
if (result == -1) {
perror(”ioctl(X25_RD_HOSTADR) call”);
exit(1);
}
The ioctl (X25_GET_IFSTATE) Call
The ioctl(X25_GET_IFSTATE) call returns the interface state.
