getsockname(2) |
 |
getsockname − get socket name
#include <sys/socket.h>
int getsockname(int s , struct sockaddr * name , socklen_t * namelen )
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).
On success, zero is returned. On error, −1 is returned, and errno is set appropriately.

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. |
SVr4, 4.4BSD (the getsockname function call appeared in 4.2BSD). SVr4 documents additional ENOMEM and ENOSR error codes.
The third argument of getsockname is in reality an ’int *’ (and this is what BSD 4.* and libc4 and libc5 have). Some POSIX confusion resulted in the present socklen_t. The draft standard has not been adopted yet, but glibc2 already follows it and also has socklen_t. See also accept(2).
