NAME

getsockname − get socket name

SYNOPSIS

getsockname(s, name, namelen)
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).

DIAGNOSTICS

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

ERRORS

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. 

SEE ALSO

bind(2), getpeername(2), socket(2)

BUGS

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