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 sockaddr_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.
