NAME

zmq_errno - retrieve value of errno for the calling thread

SYNOPSIS

int zmq_errno (void);

DESCRIPTION

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.
