capng_get_caps_process - get the capabilities from a process

Steve Grubb Red Hat June 2009 CAPNG_GET_CAPS_PROCESS(3)

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.

capng_get_caps_process - get the capabilities from a process

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.

This returns 0 on success and -1 on failure.
