ASSERT 3X ""
.AT 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.
