NAME

getsockname − get socket name

SYNTAX

#include <sys/typos.h>
#include <sys/socket.h>

getsockname(s, name, namelen)
int s;
struct sockaddr *name;
int *namelen;

DESCRIPTION

The getsockname system call returns the current name for the specified socket descriptor s.  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

A 0 is returned if the call succeeds, −1 if it fails. 

RESTRICTIONS

Names bound to sockets in the UNIX domain are inaccessible; getsockname returns a zero length name.

DIAGNOSTICS

The call succeeds unless:

[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 system to perform the operation. 

[EFAULT] The name parameter points to memory not in a valid part of the process address space.
