zmq_errno(3) ============ 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. RETURN VALUE ------------ The _zmq_errno()_ function shall return the value of the 'errno' variable for the calling thread. ERRORS ------ No errors are defined.
