NAME
bindat —
assign a local protocol address to a
socket
LIBRARY
library “libc”
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
Thebindat()
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:
- It is limited to sockets in the PF_LOCAL domain.
- 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_FDCWDnor a valid file descriptor. - [
ENOTDIR] - The sun_path field is not an absolute path and
fd is neither
AT_FDCWDnor a file descriptor associated with a directory.
