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().
