.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 run\-time library from the C run\-time library in use by 0MQ will need to use \fIzmq_errno()\fR for correct operation\&.
