NAME
getsockname - get socket nameSYNOPSIS
#include <sys/socket.h> int getsockname(int s, struct sockaddr *name, socklen_t *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).RETURN VALUE
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.ERRORS
- EBADF
- The argument s is not a valid descriptor.
- EFAULT
- The name parameter points to memory not in a valid part of the process address space.
- EINVAL
- namelen is invalid (e.g., is negative).
- ENOBUFS
- Insufficient resources were available in the system to perform the operation.
- ENOTSOCK
- The argument s is a file, not a socket.
CONFORMING TO
SVr4, 4.4BSD (the getsockname() function call appeared in 4.2BSD), POSIX.1-2001.NOTE
The third argument of getsockname() is in reality an `int *' (and this is what 4.x BSD and libc4 and libc5 have). Some POSIX confusion resulted in the present socklen_t, also used by glibc. See also accept(2).SEE ALSO
