Detailed Description

Preprocessor flags indicating which heap-backed _create()/_destroy() functions are compiled.

When CONFIG_OVE_ZERO_HEAP is not defined these macros are set to 1, enabling the corresponding heap-backed _create()/_destroy() function definitions. When zero-heap is active none of these macros are defined, and the _create()/_destroy() symbols are not declared — application code must use _init()/_deinit() with caller-supplied storage, or the OVE_*_DEFINE_STATIC() macros, both of which work in either mode.
