NAME

ZT_CMP_PTR, zt_cmp_int — construct a claim of a relation between two pointers

SYNOPSIS

#include <zt.h>

#define ZT_CMP_PTR(left, rel, right) \
  zt_cmp_ptr( \
    ZT_CURRENT_LOCATION(), \
    zt_pack_pointer((left), (#left)), \
    zt_pack_string((#rel), (#rel)), \
    zt_pack_pointer((right), (#right)))

DESCRIPTION

zt_cmp_ptr() constructs a claim of a relation between two integers. It should be used through the macro ZT_CMP_PTR() which passes source code location and packs arguments.

The relation must be either ==, or !=

IMPLEMENTATION NOTES

ZT_CMP_PTR() evaluates left and right exactly 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().
