Socketscreated with the.BR socket (3)function are initially unnamed; they areidentified only by their address family..PPThe function takes the following arguments:.TP.I socketSpecifies the file descriptor of the socket to be bound..TP.I addressPoints to a sockaddr structure containing the address to be bound to thesocket.  The length and format of the address depend on the address familyof the socket..TP.I address_lenSpecifies the length of the sockaddr structure pointed to by the addressargument..PPThe socket in use may require the process to have appropriate privilegesto use the.BR bind ()function..SH NOTES.PPAn application program can retrieve the assigned socket name with the.BR getsockname (3)function..SH CAVEATS.PPThis system call is implemented as a.B SIOCSOCKSYSIOCTL.  See.BR socksys (4)for more information..SH "RETURN VALUE".PPUpon successful completion,.BR bind ()returns 0.  Otherwise, -1 is returnedand.IR errno (3)is set to indicate the error..SH ERRORS.PPThe.BR bind ()function will fail if:.TP.RB [ EADDRINUSE ]The specified address is already in use..TP.RB [ EADDRNOTAVAIL ]The specified address is not available from the local machine..TP.RB [ EAFNOSUPPORT ]The specified address is not a valid address for the address family of thespecified socket..TP.RB [ EBADF ]The socket argument is not a valid file descriptor..TP.RB [ EFAULT ]The address argument can not be accessed..TP.RB [ EINVAL ]The socket is already bound to an address, and the protocol does notsupport binding to a new address; or the socket has been shut down..TP.RB [ ENOTSOCK ]The socket argument does not refer to a socket..TP.RB [ EOPNOTSUPP ]The socket type of the specified socket does not support binding to anaddress..PPIf the address family of the socket is.BR AF_UNIX ,then.BR bind ()will fail if:.TP.RB [ EACCES ]A component of the path prefix denies search permission, or the requested namerequires writing in a directory with a mode that denies write permission..TP.RB [ EDESTADDRREQ "] or [" EISDIR ]The address argument is a null pointer..TP.RB [ EIO ]An I/O error occurred..TP.RB [ ELOOP ]Too many symbolic links were encountered in translating the pathname inaddress..TP.RB [ ENAMETOOLONG ]A component of a pathname exceeded.RI { NAME_MAX }characters, or an entirepathname exceeded.RI { PATH_MAX }characters..TP.RB [ ENOENT ]A component of the pathname does not name an existing file or the pathnameis an empty string..TP.RB [ ENOTDIR ]A component of the path prefix of the pathname in address is not adirectory..TP.RB [ EROFS ]The name would reside on a read-only filesystem..PPThe.BR bind ()function may fail if:.TP.RB [ EACCES ]The specified address is protected and the current user does not havepermission to bind to it..TP.RB [ EINVAL ]The address_len argument is not a valid length for the address family..TP.RB [ EISCONN ]The socket is already connected..TP.RB [ ENAMETOOLONG ]Pathname resolution of a symbolic link produced an intermediate result whoselength exceeds.IR { PATH_MAX }..TP.RB [ ENOBUFS ]Insufficient resources were available to complete the call..TP.RB [ ENOSR ]There were insufficient STREAMS resources for the operation to complete..SH "SEE ALSO".PP.BR connect (3),.BR getsockname (3),.BR listen (3),.BR socket (3),.BR <sys/socket.h> (5)..SH "CONFORMING TO".PPThe Open Group XNS Issue 5.2..[xns.].\".\".[$LIST$.].TI
