capng_get_caps_process - get the capabilities from a process
#include <cap-ng.h>
int capng_get_caps_process(void);
capng_get_caps_process will get the capabilities and bounding set of the pid
stored inside libcap-ng's state table. The default is the pid of the running
process. This can be changed by using the capng_setpid function.
This returns 0 on success and -1 on failure.
If you are doing multi-threaded programming, calling this function will only get
capabilities on the calling thread. If you want to get overall capabilities
for a multi-threaded process, you can only do that before creating any
threads. Afterwards, threads may be able to independently set capabilities.
capng_get_caps_process needs a mounted /proc to read the current bounding set,
otherwise it will fail.
