NAME

     securelevel_gt, securelevel_ge — test active securelevel

SYNOPSIS

     #include <sys/types.h>
     #include <sys/proc.h>

     int
     securelevel_gt(struct ucred *cr, int level);

     int
     securelevel_ge(struct ucred *cr, int level);

DESCRIPTION

     These functions test the active security level against the given level.  If the calling
     credential cr was imprisoned by the jail(2) system call, and has a different security level
     set than the host environment, the security level with the highest value is used.

     The securelevel_gt() function will evaluate whether or not the active security level is
     greater than the supplied level.

     The securelevel_ge() function will evaluate whether or not the active security level is
     greater than or equal to the supplied level.

RETURN VALUES

     These functions return EPERM if condition evaluated to true, and 0 otherwise.
