bind(3N)

NAME
     bind - bind a name to a socket

SYNOPSIS
     #include <sys/types.h>

     bind(int s, caddr_tr name, int namelen);

DESCRIPTION
     bind() assigns a name to an unnamed socket.  When a socket is created
     with socket(3N), 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 VALUE
     If the bind is successful, a 0 value 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:

     EBADF               s is not a valid descriptor.

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

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

     EADDRINUSE          The specified address is already in use.

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

     EINVAL              The socket is already bound to an address.

     EACCES              The requested address is protected and the current
                         user has inadequate permission to access it.

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

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

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

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

     EACCES              Search permission is denied for a component of the
                         path prefix of the pathname in name.
     ELOOP               Too many symbolic links were encountered in
                         translating the pathname in name.

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

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

     EISDIR              A null pathname was specified.

SEE ALSO
     unlink(2)

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 (using
     unlink(2)).

     The rules used in name binding vary between communication domains.

     The type of address structure passed to bind() depends on the address
     family.  UNIX domain sockets (address family AF_UNIX) require a struct
     socketaddr_un as defined in sys/un.h; Internet domain sockets (address
     family AF_INET) require a struct sockaddr_in as defined in netinet/in.h.
     Other address families may require other structures.  Use the structure
     appropriate to the address family; cast the structure address to a
     generic caddr_t in the call to bind() and pass the size of the structure
     in the length argument.
