ASSERT(3X) ASSERT(3X)
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.
