.TH ASSERT 3 "$Revision$"
.ad
.SH NAME
assert \- program verification
.SH SYNOPSIS
.B #include <assert.h>
.PP
.B assert(expression)
.PP
.B _BadAssertion(fn, lino, ass)
.br
char *fn, *ass;
.br
unsigned int lino;
.SH DESCRIPTION
.PP
.I Assert
is a macro that indicates
.I expression
is expected to be true at this point in the program.
It causes a call to
.I _BadAssertion
when
.I expression
is false (0).
.PP
The routine
.I_BadAssertion
accepts three parameters:
a filename, a linenumber,
and a string representing a failed assertion.
It causes a
.IR sys_stop (S_ABORT)
with a diagnostic comment on standard error.
.PP
The assertions are disabled by defining the preprocessor constant NDEBUG.
.SH DIAGNOSTICS
.IR fn ,
line
.IR lino :
assertion
.I ass
failed.
.br
.I fn
is the source file,
.I lino
is the source line number,
and
.I ass
is the assertion
of the
.I assert
statement.
