pid of the current proc

Is there any way of intuiting the pid of the current process? If not, Lutz, is it possible to add this?

This is the pid of the newLISP process you are in:

> (import "libc.dylib" "getpid")
getpid <951021A4>
> (getpid)
1476
>

On other Unix the library is: libc.so

Here are more functions you can import from libc:

Auch!.. Yes thisone I would like to have as a newlisp variable too..

..like "ostype" you could request "main-pid" very handy instead of calling
the library's all the time (which is no problem ofcourse but more
a cosmetic issue..)

Code: Select all

newLISP v.9.3.4 on OSX IPv4 UTF-8, execute 'newlisp -h' for more info.
