NAME
       ASSERT, assert - expression verification

SYNOPSIS
       #include <sys/debug.h>

       void ASSERT(EX);

INTERFACE LEVEL
       Architecture independent level 1 (DDI/DKI).

PARAMETERS
       EX    boolean expression.

DESCRIPTION
       The ASSERT() macro checks to see if the expression EX is true. If it is not, then ASSERT() causes an error message to be logged to the con-
       sole and the system to panic. ASSERT() works only if the preprocessor symbol DEBUG is defined.

CONTEXT
       The ASSERT() macro can be used from user, interrupt, or kernel context.
