ZMQ_ERRNO(3) 0MQ Manual 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.
