SYNOPSIS
cc [ flag ... ] file ... -lxnet [ library ... ]
#include <sys/socket.h>
int getsockname(int socket, struct sockaddr *restrict address,
socklen_t *restrict address_len);
DESCRIPTION
The getsockname() function retrieves the locally-bound name of the
specified socket, stores this address in the sockaddr structure pointed
to by the address argument, and stores the length of this address in
the object pointed to by the address_len argument.
If the actual length of the address is greater than the length of the
supplied sockaddr structure, the stored address will be truncated.
If the socket has not been bound to a local name, the value stored in
the object pointed to by address is unspecified.
RETURN VALUES
Upon successful completion, 0 is returned, the address argument points
to the address of the socket, and the address_len argument points to
the length of the address. Otherwise, −1 is returned and errno is set
to indicate the error.
ERRORS
The getsockname() function will fail:
EBADF
The socket argument is not a valid file descriptor.
EFAULT
The address or address_len parameter can not be
accessed or written.
ENOTSOCK
The socket argument does not refer to a socket.
EOPNOTSUPP
The operation is not supported for this socket's proto‐
col.
The getsockname() function may fail if:
EINVAL
The socket has been shut down.
ENOBUFS
Insufficient resources were available in the system to com‐
plete the call.
ENOSR
There were insufficient STREAMS resources available for the
operation to complete.
