bind(3SOCKET)						     Sockets Library Functions						     bind(3SOCKET)

NAME

       bind - bind a name to a socket

SYNOPSIS

       cc [ flag ... ] file ... -lsocket  -lnsl  [ library ... ]
       #include <sys/types.h>
       #include <sys/socket.h>

       int bind(int s, const struct sockaddr *name, int namelen);

DESCRIPTION

       The  bind() function assigns a name to an unnamed socket. When a socket is created with socket(3SOCKET), it exists in a name space (address
       family) but has no name assigned. The bind() function requests that the name pointed to by name be assigned to the socket.

RETURN VALUES

       Upon successful completion 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The bind() function will fail if:

       EACCES		The requested address is protected, and {PRIV_NET_PRIVADDR} is not asserted in the effective set of the current process.

       EADDRINUSE	The specified address is already in use.

       EADDRNOTAVAIL	The specified address is not available on the local machine.

       EBADF		s is not a valid descriptor.

       EINVAL		namelen is not the size of a valid address for the specified address family.

       EINVAL		The socket is already bound to an address.

       ENOSR		There were insufficient STREAMS resources for the operation to complete.

       ENOTSOCK 	s is a descriptor for a file, not a socket.

       The following errors are specific to binding names in the UNIX domain:

       EACCES	  Search permission is denied for a component of the path prefix of the pathname in name.

       EIO	  An I/O error occurred while making the directory entry or allocating the inode.

       EISDIR	  A null pathname was specified.

       ELOOP	  Too many symbolic links were encountered in translating the pathname in name.

       ENOENT	  A component of the path prefix of the pathname in name does not exist.

       ENOTDIR	  A component of the path prefix of the pathname in name is not a directory.

       EROFS	  The inode would reside on a read-only file system.

NOTES

       Binding a name in the UNIX domain creates a socket in the file system that must be deleted by the caller when it is  no	longer	needed	by
       using unlink(2).

       The rules used in name binding vary between communication domains.
