You will have to duplicate its value in the Smalltalk Code. It's value is 1, in linux is defined in bits/waitflags.h as
#define WNOHANG 1
mmmmmm but then I would need to take care about its different values in different OS right? I am reading for example this thread: https://groups.google.com/forum/#!topic/comp.lang.python/_5rCpfYR_ZE
sunos 4.1.3 : #define WNOHANG 1 Solaris 2.4 : #define WNOHANG 0100 OSF1 2.0 : #define WNOHANG 0x1 Ultrix 4.4 : #define WNOHANG 1 irix 4.0.5C : #define WNOHANG 0x1 irix 5.2 : #define WNOHANG 0100 irix 6.0.1 : #define WNOHANG 0100
Exactly. I've discussed this before. Please read
http://lists.pharo.org/pipermail/pharo-dev_lists.pharo.org/2012-May/064382.h...
OK..the thread is from 1995... I thought the POSIX standard would standardize that...
I am now checking at /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/sys/wait.h
and it says: #define WNOHANG 0x00000001
But again..I wonder how portable is to stick to that...
Ok...maybe I will need to go with a VM primitive as #primGetChildExitStatus: that way I can do the:
self cCode: 'waitpid ( pidToHandle, &exitStatus, WNOHANG )' inSmalltalk: [ exitStatus := -1 ].
pd: que groso Pablito verte por aca!!!!
Cheers, Pablo

Say I want to call to waitpid like this:
waitpid(childID, &status, WNOHANG);
How can I do since I don't have access to WNOHANG int value in order to send it via argument .... ???
Any idea?
Thanks in advance,
