PR_CAPBSET_READ(2const)                          PR_CAPBSET_READ(2const)

ИМЯ

       PR_CAPBSET_READ - read the calling thread's capability bounding
       set

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <linux/prctl.h>  /* Definition of PR_* constants */
       #include <sys/prctl.h>

       int prctl(PR_CAPBSET_READ, long cap);

ОПИСАНИЕ

       Return 1 if the capability specified in cap is in the calling
       thread's capability bounding set, or 0 if it is not.

       The capability constants are defined in <linux/capability.h>.

       The capability bounding set dictates whether the process can
       receive the capability through a file's permitted capability set
       on a subsequent call to execve(2).

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, this call returns the boolean value described above.
       On error, -1 is returned, and errno is set to indicate the error.

ОШИБКИ

       EINVAL cap does not specify a valid capability.

ВЕРСИИ

       A higher-level interface layered on top of this operation is
       provided in the libcap(3) library in the form of
       cap_get_bound(3).

СТАНДАРТЫ

       Linux.

ИСТОРИЯ

       Linux 2.6.25.
