getsockname(2)getsockname(2)Namegetsockname - get socket name
Syntax
#include <sys/types.h>
#include <sys/socket.h>
getsockname(s, name, namelen)
int s;
struct sockaddr *name;
int *namelen;
Description
The 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, in bytes, of the name returned.
Return Values
A zero is returned if the call succeeds, -1 if it fails.
Restrictions
Names bound to sockets in the UNIX domain are inaccessible; 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.
