ASSERT(3C)              COMMAND REFERENCE              ASSERT(3C)



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 is the source
                         line number of the assert statement.

SEE ALSO
     intro(3f).
