Re: [Oorexx-devel] OS Specific Classes/Functions Discussion

[David A. <dav...@gm...>]

On further reflection, one of the things that might make this whole 
thing easier is if the ::method and ::routine directives could define 
the same method name multiple times in a class. Then use an operating 
system keyword to determine which method is used. Something along the 
line of

::METHOD getpid EXTERNAL "LIBRARY rexxutil SysGetpid" ENV WINDOWS
::METHOD getpid EXTERNAL "LIBRARY orxgenprocess SysGetpid" ENV LINUX
::METHOD getpid EXTERNAL "LIBRARY orxgenprocess SysGetpid" ENV MAC
::METHOD getpid EXTERNAL "LIBRARY orxgenprocess SysGetpid" ENV AIX
::METHOD getpid ENV UNKNOWN
return 0

If a no OS keyword matched the current runtime environment then the 
UNKNOWN environment would be used (if defined). If the UNKNOWN 
environment name was not defined then no method of that name would be 
defined for the class. This way a single class definition could be used 
to cover all platforms.
