CAPNG_APPLY(3)                  Libcap-ng API                 CAPNG_APPLY(3)

NAME         top

       capng_apply - apply the stored capabilities settings

SYNOPSIS         top

       #include <cap-ng.h>

       int capng_apply(capng_select_t set);

DESCRIPTION         top

       capng_apply will transfer the specified internal posix capabilities
       settings to the kernel. The options are CAPNG_SELECT_CAPS for the
       traditional capabilities, CAPNG_SELECT_BOUNDS for the bounding set,
       or CAPNG_SELECT_BOTH if transferring both is desired.

RETURN VALUE         top

       This returns 0 on success and -1 on failure.

NOTES         top

       If you are doing multi-threaded programming, calling this function
       will only set capabilities on the calling thread. All other threads
       are unaffected. If you want to set overall capabilities for a multi-
       threaded process, you will need to do that before creating any
       threads. See the capset syscall for more information on this topic.
