cc [ flag ... ] file ... -lsocket -lnsl [ library ... ] #include <sys/types.h> #include <sys/socket.h>int bind(int s, const struct sockaddr *name, int namelen);
bind() 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. bind() requests that the name pointed to by name be assigned to the socket.
If the bind is successful, 0 is returned. A return value of -1 indicates an error, which is further specified in the global errno.
The bind() call will fail if:
The requested address is protected and the current user has inadequate permission to access it.
The specified address is already in use.
The specified address is not available on the local machine.
s is not a valid descriptor.
namelen is not the size of a valid address for the specified address family.
The socket is already bound to an address.
There were insufficient STREAMS resources for the operation to complete.
s is a descriptor for a file, not a socket.
The following errors are specific to binding names in the UNIX domain:
Search permission is denied for a component of the path prefix of the pathname in name.
An I/O error occurred while making the directory entry or allocating the inode.
A null pathname was specified.
Too many symbolic links were encountered in translating the pathname in name.
A component of the path prefix of the pathname in name does not exist.
A component of the path prefix of the pathname in name is not a directory.
The inode would reside on a read-only file system.

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 (using unlink(2)).
The rules used in name binding vary between communication domains.
