Check if any running binary is 32 or 64 bit

问题

It is possible to check if an app bundle's binary process is running in 32 or 64 bit mode, as answered in this question, but I can verify that it only works with GUI processes.

However, I need to also check processes that don't have a GUI and is not part of a bundle.

So, programmatically, without calling system functions or other executables, how can I test if any process is running in 32 or 64 bit mode, given the process pid?

回答1:

Ok, so I finally found the answer was already on SO here, for Carbon. In order to use that code now, this include is required:

#include <sys/sysctl.h>

Also, it appears that the member to the process structure has changed from

proc->kp_proc.p_flags 

to this:

proc->kp_proc.p_flag
