getsockname — get socket name
SYNOPSIS
#include <sys/socket.h>
int
getsockname(int s, struct sockaddr *name, int *namelen);
DESCRIPTIONGetsockname() 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 ALSObind(2), socket(2)BUGS
Names bound to sockets in the UNIX domain are inaccessible; getsockname
returns a zero length name.
