Function
Documented validity of a Transform2D.
Declaration
Declaration
inline bool transform2d_valid(const Transform2D& transform)Documented validity of a Transform2D.
| Parameter | Type | Meaning |
|---|---|---|
transform | const Transform2D & | Value supplied for transform. Keep referenced or pointed-to data valid for the complete call. |
Returns: bool. Check the value before continuing when it represents success, availability or a resource handle.
Example
C++ example
#include "world2d.hpp"
// Assume these named values have been initialized with valid data:
// const Transform2D & transform
auto result = epok::transform2d_valid(transform);Trade-offs and warnings
Check the return value; `false` is part of normal control flow for many PSX resource operations. Pointer/reference arguments are borrowed unless the source contract says otherwise; keep them valid for the complete operation and never assume null is accepted.
Declared in runtime/world2d.hpp:51
