bind(3SOCKET) Sockets Library Functions bind(3SOCKET)NAMEbind - bind a name to a socket
SYNOPSIS
cc [ flag ... ] file ... -lsocket-lnsl [ library ... ]
#include <sys/types.h>
#include <sys/socket.h>
int bind(int s, const struct sockaddr *name, int namelen);
DESCRIPTION
The bind() function assigns a name to an unnamed socket. When a socket
is created with socket(3SOCKET), it exists in a name space (address
family) but has no name assigned. The bind() function requests that the
name pointed to by name be assigned to the socket.
RETURN VALUES
Upon successful completion 0 is returned. Otherwise, −1 is returned and
errno is set to indicate the error.
ERRORS
The bind() function will fail if:
EACCES The requested address is protected, and {PRIV_NET_PRI‐
VADDR} is not asserted in the effective set of the
current process.
EADDRINUSE The specified address is already in use.
EADDRNOTAVAIL The specified address is not available on the local
machine.
EBADF s is not a valid descriptor.
EINVAL namelen is not the size of a valid address for the
specified address family.
EINVAL The socket is already bound to an address.
ENOSR There were insufficient STREAMS resources for the
operation to complete.
ENOTSOCK s is a descriptor for a file, not a socket.
The following errors are specific to binding names in the UNIX domain:
EACCES Search permission is denied for a component of the path pre‐
fix of the pathname in name.
EIO An I/O error occurred while making the directory entry or
allocating the inode.
EISDIR A null pathname was specified.
ELOOP Too many symbolic links were encountered in translating the
pathname in name.
ENOENT A component of the path prefix of the pathname in name does
not exist.
ENOTDIR A component of the path prefix of the pathname in name is
not a directory.
EROFS The inode would reside on a read-only file system.

socket.h(3HEAD)NOTES
Binding a name in the UNIX domain creates a socket in the file system
that must be deleted by the caller when it is no longer needed by using
unlink(2).
The rules used in name binding vary between communication domains.
