NAME
|
||
|
|
----

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
|
||
|
|
runtime library from the C runtime 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
|
||
|
|
------------
|

|

|
||
