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.
