GETSOCKNAME(2) Linux Programmer's Manual GETSOCKNAME(2)
NAME
getsockname - get socket name
SYNOPSIS
int getsockname(int s , struct sockaddr * name , int *
namelen )
DESCRIPTION
Getsockname returns the current name for the specified
socket. The namelen parameter should be initialized to
indicate the amount of space pointed to by name. On
return it contains the actual size of the name returned
(in bytes).
RETURN VALUE
On success, zero is returned. On error, -1 is returned,
and errno is set appropriately. A 0 is returned if the
call succeeds, -1 if it fails.
ERRORS
EBADF The argument s is not a valid descriptor.
ENOTSOCK
The argument s is a file, not a socket.
ENOBUFS Insufficient resources were available in the sys-
tem to perform the operation.
EFAULT The name parameter points to memory not in a valid
part of the process address space.
CONFORMING TO
SVr4, 4.4BSD (the getsockname function call appeared in
4.2BSD). SVr4 documents additional ENOMEM and ENOSR error
codes.
