BINDAT(2)		  FreeBSD System Calls Manual		     BINDAT(2)

NAME
     bindat -- assign a	local protocol address to a socket

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <sys/types.h>
     #include <sys/socket.h>

     #include <fcntl.h>

     int
     bindat(int	fd, int	s, const struct	sockaddr *addr,	socklen_t addrlen);

DESCRIPTION
     The bindat() system call assigns the local	protocol address to a socket.
     When passed the special value AT_FDCWD in the fd parameter, the behavior
     is	identical to a call to bind(2).	 Otherwise, bindat() works like	the
     bind(2) system call with two exceptions:

	   1.	It is limited to sockets in the	PF_LOCAL domain.

	   2.	If the file path stored	in the sun_path	field of the sock-
		addr_un	structure is a relative	path, it is located relative
		to the directory associated with the file descriptor fd.

RETURN VALUES
     The bindat() function returns the value 0 if successful; otherwise	the
     value -1 is returned and the global variable errno	is set to indicate the
     error.

ERRORS
     The bindat() system call may fail with the	same errors as the bind(2)
     system call or with the following errors:

     [EBADF]		The sun_path field does	not specify an absolute	path
			and the	fd argument is neither AT_FDCWD	nor a valid
			file descriptor.

     [ENOTDIR]		The sun_path field is not an absolute path and fd is
			neither	AT_FDCWD nor a file descriptor associated with
			a directory.

SEE ALSO
     bind(2), connectat(2), socket(2), unix(4)

AUTHORS
     The bindat	was developed by Pawel Jakub Dawidek <pawel@dawidek.net> under
     sponsorship from the FreeBSD Foundation.
