+== NAME
+
+nn_bind - accept connections from remote peers (compatible API)
+
+== SYNOPSIS
+
+[source, c]
+----
+#include <nanomsg/nn.h>
+
+int nn_bind(int sock, const char *url)
+----
+
+== DESCRIPTION
+
+The `nn_bind()` function arranges for the socket _sock_ to
+accept connections at the address specified by _url_.
+An "`endpoint identifier`" for this socket's association with the _url_ is
+returned to the caller on success.
+This ID can be used with `<<nn_shutdown.3compat#,nn_shutdown()>>`` to
+"`unbind`" the socket from the address at _url_.
+
+NOTE: This function is provided for API
+<<nng_compat.3compat#,compatibility>> with legacy _libnanomsg_.
+Consider using the relevant <<libnng.3#,modern API>> instead.
+
+NOTE: The bind operation is performed asynchronously, and may not have
+completed before this function returns control to the caller.
+
+IMPORTANT: Only transports supported by legacy _libnanomsg_ may be
+used with this function.
+In particular, only the schemes `tcp://`, `ipc://`, `inproc://`, and `ws://` are
+supported with this function.
+(Use the <<libnng.3#,modern API>> to use other schemes.)
+
+== RETURN VALUES
+
+This function returns a positive identifier on success, and -1 on error.
+
+== ERRORS
+
+[horizontal]
+`EADDRINUSE`:: The address specified by _url_ is already in use.
+`EADDRNOTAVAIL`:: The address specified by _url_ is not available.
+`EBADF`:: The socket _sock_ is not open.
+`EINVAL`:: An invalid _url_ was supplied.
