securelevel_gt, securelevel_ge — test active securelevel
#include <sys/types.h> #include <sys/proc.h> int securelevel_gt(struct ucred *cr, int level); int securelevel_ge(struct ucred *cr, int level);
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.
These functions return EPERM if condition evaluated to true, and 0 otherwise.
