Declaration
Declaration
bool reserve(Handle h,uint16_t from,uint16_t to)Performs `reserve` as part of the navigation module.
| Parameter | Type | Meaning |
|---|---|---|
h | Handle | Value supplied for h. Keep referenced or pointed-to data valid for the complete call. |
from | uint16_t | Value supplied for from. Keep referenced or pointed-to data valid for the complete call. |
to | uint16_t | Value supplied for to. 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 "navigation.hpp"
// Assume these named values have been initialized with valid data:
// Handle h
// uint16_t from
// uint16_t to
epok::nav::World& object = /* obtain a valid instance */;
auto result = object.reserve(h, from, to);Trade-offs and warnings
Check the return value; `false` is part of normal control flow for many PSX resource operations.
