CAPNG_GET_CAPS_PROCESS(3)     Libcap-ng API    CAPNG_GET_CAPS_PROCESS(3)

NAME

       capng_get_caps_process - get the capabilities from a process

SYNOPSIS

       #include <cap-ng.h>

       int capng_get_caps_process(void);

DESCRIPTION

       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.

RETURN VALUE

       This returns 0 on success and -1 on failure.

NOTES

       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.
