Purpose
Gets the system sensitivity and integrity labels.
Library
Standard C library (libc.a)
Syntax
#include <sys/mac.h>
int sec_getsyslab (minsl, maxsl, mintl, maxtl)
sl_t *minsl;
sl_t *maxsl;
tl_t *mintl;
tl_t *maxtl;
Description
The sec_getsyslab subroutine gets the system minimum and maximum sensitivity labels and the system minimum and maximum integrity labels that are being used by the kernel. If the minsl, maxsl, mintl, or maxtl parameter is a null pointer, the corresponding label is not retrieved. If the maxsl or maxtl parameter is requested, either the calling process clearance must dominate the system maximum sensitivity label or integrity label, or the process must have the PV_KER_SECCONFIG or PV_MAC_R privilege.
