Hi, Mehmet Fatih AKBULUT wrote: > how can i find a running process' pid with using cpp ? CPP stands for « C Preprocessor »: « The C preprocessor implements the macro language used to transform C, C++, and Objective-C programs before they are compiled. It can also be useful on its own. » If your question is how do I get the PID of the current process in a userspace application, then you're on the wrong list.
