bind - bind a name to a socket
Návod, kniha: POSIX Programmer's Manual
#include <sys/socket.h>
int bind(int
socket, const struct sockaddr
*address,
socklen_t
address_len );
The
bind() function shall assign a local socket address
address to
a socket identified by descriptor
socket that has no local socket
address assigned. Sockets created with the
socket() function are
initially unnamed; they are identified only by their address family.
The
bind() function takes the following arguments:
- socket
- Specifies the file descriptor of the socket to be
bound.
- address
- Points to a sockaddr structure containing the
address to be bound to the socket. The length and format of the address
depend on the address family of the socket.
- address_len
- Specifies the length of the sockaddr structure
pointed to by the address argument.
The socket specified by
socket may require the process to have
appropriate privileges to use the
bind() function.
Upon successful completion,
bind() shall return 0; otherwise, -1 shall be
returned and
errno set to indicate the error.
The
bind() function shall fail if:
- EADDRINUSE
- The specified address is already in use.
- EADDRNOTAVAIL
- The specified address is not available from the local
machine.
- EAFNOSUPPORT
- The specified address is not a valid address for the
address family of the specified socket.
- EBADF
- The socket argument is not a valid file
descriptor.
- EINVAL
- The socket is already bound to an address, and the protocol
does not support binding to a new address; or the socket has been shut
down.
- ENOTSOCK
- The socket argument does not refer to a socket.
- EOPNOTSUPP
- The socket type of the specified socket does not support
binding to an address.
If the address family of the socket is AF_UNIX, then
bind() shall fail
if:
- EACCES
- A component of the path prefix denies search permission, or
the requested name requires writing in a directory with a mode that denies
write permission.
- EDESTADDRREQ or EISDIR
- The address argument is a null pointer.
- EIO
- An I/O error occurred.
- ELOOP
- A loop exists in symbolic links encountered during
resolution of the pathname in address.
- ENAMETOOLONG
- A component of a pathname exceeded {NAME_MAX} characters,
or an entire pathname exceeded {PATH_MAX} characters.
- ENOENT
- A component of the pathname does not name an existing file
or the pathname is an empty string.
- ENOTDIR
- A component of the path prefix of the pathname in
address is not a directory.
- EROFS
- The name would reside on a read-only file system.
The
bind() function may fail if:
- EACCES
- The specified address is protected and the current user
does not have permission to bind to it.
- EINVAL
- The address_len argument is not a valid length for
the address family.
- EISCONN
- The socket is already connected.
- ELOOP
- More than {SYMLOOP_MAX} symbolic links were encountered
during resolution of the pathname in address.
- ENAMETOOLONG
- Pathname resolution of a symbolic link produced an
intermediate result whose length exceeds {PATH_MAX}.
- ENOBUFS
- Insufficient resources were available to complete the call.
