       Standard C library (libc, -lc)


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

       int prctl(PR_CAP_AMBIENT, long op, ...);


DESCRIPTION
       Reads  or  changes  the ambient capability set of the calling thread, according to the value of op, which
       must be one of the following:

       PR_CAP_AMBIENT_RAISE
       PR_CAP_AMBIENT_LOWER
       PR_CAP_AMBIENT_IS_SET
       PR_CAP_AMBIENT_CLEAR_ALL


RETURN VALUE
       On success, a nonnegative value is returned.  On error, -1 is returned, and errno is set to indicate  the
       error.


ERRORS
       EINVAL op is not a valid value.


VERSIONS
       Higher-level  interfaces  layered on top of the above operations are provided in the libcap(3) library in
       the form of cap_get_ambient(3), cap_set_ambient(3), and cap_reset_ambient(3).
