NAME

       getsockname - get socket name

SYNOPSIS

       #include <sys/socket.h>

       int getsockname(int sockfd, struct sockaddr *addr, socklen_t *addrlen);

DESCRIPTION

       getsockname()  returns  the current address to which the socket sockfd is bound, in the buffer pointed to
       by addr.  The addrlen argument should be initialized to indicate the amount of space (in  bytes)  pointed
       to by addr.  On return it contains the actual size of the socket address.

       The  returned address is truncated if the buffer provided is too small; in this case, addrlen will return
       a value greater than was supplied to the call.

RETURN VALUE

       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

ERRORS

       EBADF  The argument sockfd is not a valid file descriptor.

       EFAULT The addr argument points to memory not in a valid part of the process address space.

       EINVAL addrlen is invalid (e.g., is negative).

       ENOBUFS
              Insufficient resources were available in the system to perform the operation.

       ENOTSOCK
              The file descriptor sockfd does not refer to a socket.

CONFORMING TO

       POSIX.1-2001, POSIX.1-2008, SVr4, 4.4BSD (getsockname() first appeared in 4.2BSD).

NOTES

       For background on the socklen_t type, see accept(2).
