bind - bind a name to a socket
!!SYNOPSIS

-#include __

__#include <sys/types.h>
__
+ __
#include <sys/socket.h>
__
+ __int bind(int__ ''sockfd''__, struct sockaddr *__''my_addr''__, socklen_t__ ''addrlen''__);__
-__int bind(int__ ''sockfd''__, struct sockaddr
-*__''my_addr''__, socklen_t__
-''addrlen''__);__
!!DESCRIPTION
+__bind__ gives the socket ''sockfd'' the local address ''my_addr''. ''my_addr'' is ''addrlen'' bytes long. Traditionally, this is called ``assigning a name to a socket.'' When a socket is created with socket(2), it
+exists in a name space (address family) but has no name assigned.
+It is normally necessary to assign a local address using __bind__ before a __SOCK_STREAM__ socket may receive connections (see accept(2)).

!!NOTES
+The rules used in name binding vary between address families. Consult the manual entries in Section 7 for detailed information. For __AF_INET__ see ip(7), for __AF_UNIX__ see unix(7), for __AF_APPLETALK__ see ddp(7), for __AF_PACKET__ see packet(7), for __AF_X25__ see x25(7) and for __AF_NETLINK__ see netlink(7).

!!RETURN VALUE

-
-
+On success, zero is returned. On error, -1 is returned, and ''errno'' is set appropriately.
!!ERRORS
+;[EBADF]: ''sockfd'' is not a valid descriptor.
+;[EINVAL]: The socket is already bound to an address. This may change in the future: see ''linux/unix/sock.c'' for details.
+;[EACCES]: The address is protected, and the user is not the super-user.
+;[ENOTSOCK]: Argument is a descriptor for a file, not a socket.
-__EBADF
__
+The following errors are specific to UNIX domain (
__AF
_UNIX
__) sockets:
+;[EINVAL]: The ''addrlen'' is wrong, or the socket was not in the __AF_UNIX__ family.
+;[EROFS]: The socket inode would reside on a read-only file system.
+;[EFAULT]: ''my_addr'' points outside the user's accessible address space.
+;[ENAMETOOLONG]: ''my_addr'' is too long.
+;[ENOENT]: The file does not exist.
+;[ENOMEM]: Insufficient kernel memory was available.
+;[ENOTDIR]: A component of the path prefix is not a directory.
+;[EACCES]: Search permission is denied on a component of the path prefix.
+;[ELOOP]: Too many symbolic links were encountered in resolving ''my_addr''.

!!NOTE
+The third argument of __bind__ 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).
