PR_CAP_AMBIENT(2const) PR_CAP_AMBIENT(2const)
PR_CAP_AMBIENT - read or change the ambient capability set of the calling thread
Standard C library (libc, -lc)
#include <linux/prctl.h> /* Definition of PR_* constants */ #include <sys/prctl.h> int prctl(PR_CAP_AMBIENT, long op, ...);
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
On success, a nonnegative value is returned. On error, -1 is returned, and errno is set to indicate the error.
EINVAL op is not a valid value.
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).
