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.  It works just 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 sockaddr_un structure is a relative path,
                it is located relative to the directory associated with the file descriptor fd.  If bindat() is
                passed the special value AT_FDCWD in the fd parameter, the current working directory is used and
                the behavior is identical to a call to bind(2).

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 for a UNIX domain socket
     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.
