GETSOCKNAME(2) MachTen 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 re-
turned (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 per-
form the operation.

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

SEE ALSO
bind(2), socket(2)

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

HISTORY
The getsockname function call appeared in 4.2BSD.
