Is there a way of getting the process id of my C++ application?

问题

Is there a way of getting the process id of my C++ application? I am using the Carbon framework, but not Cocoa…

回答1:

can you use the getpid() function found in unistd.h ?

osx reference

回答2:

GetProcessPID is what you need. This takes a ProcessSerialNumber, which you can obtain from GetCurrentProcess.

回答3:

Note that you don't actually need to call GetCurrentProcess, you can use the constant kCurrentProcess.

(But getpid is a lot less work if you're not trying to access another process's PID, anyway.)
