       security_getenforce, security_setenforce, security_deny_unknown - get or set the enforcing state of SELinux

SYNOPSIS
       #include <selinux/selinux.h>

       int security_getenforce(void);

       int security_setenforce(int value);

       int security_deny_unknown(void);

DESCRIPTION
       security_getenforce() returns 0 if SELinux is running in permissive mode, 1 if it is running in enforcing mode, and -1 on error.

       security_setenforce()  sets  SELinux  to  enforcing mode if the value 1 is passed in, and sets it to permissive mode if 0 is passed in.	On
       success 0 is returned, on error -1 is returned.

       security_deny_unknown() returns 0 if SELinux treats policy queries on undefined object classes or permissions as being allowed, 1  if  such
       queries are denied, and -1 on error.
