Syntax for getpeername()
getpeername() and its parameters are described below.
#include <sys/types.h>
#include <sys/socket.h>
#include <x25/x25addrstr.h>
int error;
int sd, addrlen;
struct x25addrstr addr;
addrlen = sizeof(struct x25addrstr);
error = getpeername(sd, &addr, addrlen);
sd Socket descriptor for the socket whose peer address will be returned.
addr If the call completes successfully, this x25addrstr structure contains the
X.121 address of the remote DTE. This information is useful when using
wildcard addressing and when reestablishing a terminated connection.
addrlen If the call completes successfully, addrlen contains the length in bytes of
the x25addrstr structure pointed to by addr . Before calling
getpeername(), this field must be initialized with the size of the
x25addrstr structure.
error If the call completes successfully, error contains 0. Otherwise, –1 is
returned and errno contains the cause of the error.
Refer to the getsockname(2) entry in your man pages for more
information.
Syntax for getsockname()
The getsockname() and its parameters are described below.
#include <sys/types.h>
#include <sys/socket.h>
#include <x25/x25addrstr.h>
int error;
int sd, addrlen;
struct x25addrstr addr;
addrlen = sizeof(struct x25addrstr);
error = getsockname(sd, &addr, &addrlen);
sd Socket descriptor for the socket whose addressing information is being
