Hello Mariano,��

�� �� ��WNOHANG is a constant is defined in sys/wait.h, after the compilation is not included in the object file.��

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

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

Hi guys,

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,��
