CAP_CLEAR(3)			    Linux Programmer's Manual			     CAP_CLEAR(3)

       cap_clear, cap_get_flag, cap_set_flag - capability data object manipulation

       #include <sys/capability.h>

       int cap_clear(cap_t cap_p);

       int   cap_get_flag(cap_t   cap_p,   cap_value_t	cap,  cap_flag_t  flag,  cap_flag_value_t

       int  cap_set_flag(cap_t	 cap_p,   cap_flag_t   flag,   int   ncap,   cap_value_t   *caps,
       cap_flag_value_t value);

       cc ... -lcap

       cap_clear  initializes the capability state in working storage identified by cap_p in such
       a way that all capability flags are cleared.

       cap_get_flag obtains the current value of the capability flag, flag,  of  the  capability,
       cap,  from  the capability state identified by cap_p and places it in the location pointed
       to by value_p.

       cap_set_flag sets the flag, flag, of each capability in the array caps in  the  capability
       state  identified by cap_p to value.  The argument, ncap, is used to specify the number of
       capabilities in the array, caps.

       A cap_value_t can identify any capability, such as CAP_CHOWN.  A cap_flag_t can be set  to
       CAP_EFFECTIVE,  CAP_INHERITABLE or CAP_PERMITTED.  A cap_flag_value_t can be CAP_CLEAR (0)
       or CAP_SET (1).

       cap_clear, cap_get_flag and cap_set_flag return zero on success, and -1 on failure.

       On failure, errno(3) is set to EINVAL, indicating that one of the arguments is invalid.

       These functions are specified by POSIX.1e.
