ASSERT(3)	    UNIX Programmer's Manual		ASSERT(3)


NAME
     assert - program verification

SYNOPSIS
     #include <assert.h>

     assert(expression)

DESCRIPTION
     Assert is a macro that indicates expression is expected to
     be true at this point in the program.  It causes an exit(2)
     with a diagnostic comment on the standard output when
     expression is false (0).  Compiling with the cc(1) option
     -DNDEBUG effectively deletes assert from the program.

DIAGNOSTICS
     `Assertion failed: file f line n.' F is the source file and
     n the source line number of the assert statement.
