int zmq_errno (void);
The zmq_errno() function shall retrieve the value of the errno variable for the calling thread.
The zmq_errno() function is provided to assist users on non-POSIX systems who are experiencing issues with retrieving the correct value of errno directly. Specifically, users on Win32 systems whose application is using a different C runtime library from the C runtime library in use by 0MQ will need to use zmq_errno() for correct operation.
Users not experiencing issues with retrieving the correct value of errno should not use this function and should instead access the errno variable directly.
The zmq_errno() function shall return the value of the errno variable for the calling thread.
No errors are defined.
