NAME

6       zmq_errno - retrieve value of errno for the calling thread
7

SYNOPSIS

9       int zmq_errno (void);
10

DESCRIPTION

12       The zmq_errno() function shall retrieve the value of the errno variable
13       for the calling thread.
14
15       The zmq_errno() function is provided to assist users on non-POSIX
16       systems who are experiencing issues with retrieving the correct value
17       of errno directly. Specifically, users on Win32 systems whose
18       application is using a different C run-time library from the C run-time
19       library in use by 0MQ will need to use zmq_errno() for correct
20       operation.
21
22           Important
23           Users not experiencing issues with retrieving the correct value of
24           errno should not use this function and should instead access the
25           errno variable directly.
26

RETURN VALUE

28       The zmq_errno() function shall return the value of the errno variable
29       for the calling thread.
30

ERRORS

32       No errors are defined.
