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 param‐ eter, 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.
