SYNOPSIS
#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() to
“unbind” the socket from the address at url.
| This function is provided for API compatibility with legacy libnanomsg. Consider using the relevant modern API instead. |
| The bind operation is performed asynchronously, and may not have completed before this function returns control to the caller. |
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 modern API to use other schemes.)
|
RETURN VALUES
This function returns a positive identifier on success, and -1 on error.
ERRORS
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. |
