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
bind() 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. bind() requests that the name pointed to by name be assigned to the socket. RETURN VALUES
If the bind is successful, 0 is returned. A return value of -1 indicates an error, which is further specified in the global errno. ERRORS
The bind() call 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. ATTRIBUTES

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 byus- ing unlink(2). The rules used in name binding vary between communication domains. SunOS 5.10 20 Feb 2003 bind(3SOCKET)

bind - bind a name to a socket SYNOPSIS
cc [ flag ... ] file ... -lxnet [ library ... ] #include <sys/socket.h> int bind(int socket, const struct sockaddr *address, socklen_t address_len); DESCRIPTION
The bind() function assigns an address to an unnamed socket. Sockets created with socket(3XNET) function are initially unnamed. They are identified only by their address family. The function takes the following arguments: socket Specifies the file descriptor of the socket to be bound. address Points to a sockaddr structure containing the address to be bound to the socket. The length and format of the address depend on the address family of the socket. address_len Specifies the length of the sockaddr structure pointed to by the address argument. The socket in use may require the process to have appropriate privileges to use the bind() function. USAGE
An application program can retrieve the assigned socket name with the getsockname(3XNET) function. RETURN VALUES
Upon successful completion, bind() returns 0. Otherwise, -1 is returned and errno is set to indicate the error. ERRORS
The bind() function will fail if: EADDRINUSE The specified address is already in use. EADDRNOTAVAIL The specified address is not available from the local machine. EAFNOSUPPORT The specified address is not a valid address for the address family of the specified socket. EBADF The socket argument is not a valid file descriptor. EFAULT The address argument can not be accessed. EINVAL The socket is already bound to an address, and the protocol does not support binding to a new address; or the socket has been shut down. ENOTSOCK The socket argument does not refer to a socket. EOPNOTSUPP The socket type of the specified socket does not support binding to an address. If the address family of the socket is AF_UNIX, then bind() will fail if: EACCES A component of the path prefix denies search permission, or the requested name requires writing in a directory with a mode that denies write permission. EDESTADDRREQ The address argument is a null pointer. EISDIR EIO An I/O error occurred. ELOOP Too many symbolic links were encountered in translating the pathname in address. ENAMETOOLONG A component of a pathname exceeded NAME_MAX characters, or an entire pathname exceeded PATH_MAX characters. ENOENT A component of the pathname does not name an existing file or the pathname is an empty string. ENOTDIR A component of the path prefix of the pathname in address is not a directory. EROFS The name would reside on a read-only filesystem. The bind() function may fail if: EACCES The specified address is protected, and {PRIV_NET_PRIVADOR} is not asserted in the effective set of the current process. EINVAL The address_len argument is not a valid length for the address family. EISCONN The socket is already connected. ENAMETOOLONG Pathname resolution of a symbolic link produced an intermediate result whose length exceeds PATH_MAX. ENOBUFS Insufficient resources were available to complete the call. ENOSR There were insufficient STREAMS resources for the operation to complete. ATTRIBUTES
