NAME

getsockname − get socket name

SYNOPSIS

#include <sys/types.h>
#include <sys/socket.h>
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 or the namelen parameter point to memory not in a valid part of the process address space. 

[EINVAL] The namelen parameter specifies a buffer size which is negative or is larger than the largest buffer accepted by the system call.
