NAME

     ZT_FALSE, zt_false — construct a claim that a value is false

SYNOPSIS

     #include <zt.h>

     #define ZT_FALSE(value) \
       zt_false( \
         ZT_CURRENT_LOCATION(), \
         zt_pack_boolean((value), #value)) \

     zt_claim
     zt_false(zt_location location, zt_value value);

DESCRIPTION

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

     zt_false() 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_FALSE() evaluates value only once.

RETURN VALUES

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