NAME

ZT_TRUE, zt_true — construct a claim that a value is true

SYNOPSIS

#include <zt.h>

#define ZT_TRUE(value) \
zt_true( \
ZT_CURRENT_LOCATION(), \
zt_pack_boolean((value), #value)) \

zt_claim

zt_true(zt_location location, zt_value value);

DESCRIPTION

zt_true() constructs a claim that a given value is true. It should be used through the macro ZT_TRUE(), which passes source code location and packs argument.

zt_true() can be used to check custom properties by calling arbitrary verification logic. The disadvantage of this approach is that on failure, the error message cannot precisely explain the problem.

IMPLEMENTATION NOTES

ZT_TRUE() evaluates value only once.

RETURN VALUES

Both the macro and the function return a zt_claim structure with the appropriate attributes set. The returned claim is usually passed to zt_check() or to zt_assert().
