+.SH "NAME"
+zmq_errno \- retrieve value of errno for the calling thread
+.SH "SYNOPSIS"
+.sp
+\fBint zmq_errno (void);\fR
+.SH "DESCRIPTION"
+.sp
+The \fIzmq_errno()\fR function shall retrieve the value of the \fIerrno\fR variable for the calling thread\&.
+.sp
+The \fIzmq_errno()\fR function is provided to assist users on non\-POSIX systems who are experiencing issues with retrieving the correct value of \fIerrno\fR 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 \fIzmq_errno()\fR for correct operation\&.
