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 independantly set capabilities.

capng_get_caps_process needs a mounted /proc to read the current bounding set, otherwise it will fail.

*capng_setpid*(3), *capabilities*(7)
