Return the path of the selinux policy files for this machine selinux_set_policy_root - set an alternate selinux root path for the selinux policy files for this machine.
#include <selinux/selinux.h>
const char *selinux_policy_root(void);
int selinux_set_policy_root(const char *policypath);
selinux_policy_root() reads the contents of the /etc/selinux/config file to determine which policy files should be used for this machine. selinux_set_policy_root() sets up all all policy paths based on the alternate root
/etc/selinux/config file to determine which policy files should be used for this machine.
On success, selinux_policy_root returns a directory path containing the SELinux policy files. On failure, selinux_policy_root returns NULL.
On success, selinux_set_policy_root returns 0 on success -1 on failure.
