GETSOCKNAME(2) DragonFly System Calls Manual GETSOCKNAME(2)
NAME
getsockname -- get socket name
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <sys/socket.h>
int
getsockname(int s, struct sockaddr *name, socklen_t *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 VALUES
The getsockname() function returns the value 0 if successful; otherwise
the value -1 is returned and the global variable errno is set to indicate
the error.
ERRORS
The call succeeds unless:
[EBADF] The argument s is not a valid descriptor.
[ECONNRESET] The connection has been reset by the peer.
[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)
HISTORY
The getsockname() function call appeared in 4.2BSD.
BUGS
Names bound to sockets in the UNIX domain are inaccessible; getsockname
returns a zero length name.
