zmq_errno — retrieve value of errno for the calling thread 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 run-time library from the C run-time library in use by 0MQ will need to use zmq_errno() for correct operation. Important 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. This page was written by the 0MQ community.
