Why use it
The boolean result makes success, availability or state explicit without exceptions.

epok::instrument::synth::detail::source_changed
Function · 1 overload
Function
Performs `source changed` as part of the instrument synth module.
Declaration
Declaration
inline bool source_changed(uint16_t source,const Controls& a,const Controls& b)Performs `source changed` as part of the instrument synth module.
| Parameter | Type | Meaning |
|---|---|---|
source | uint16_t | Value supplied for source. Keep referenced or pointed-to data valid for the complete call. |
a | const Controls & | Value supplied for a. Keep referenced or pointed-to data valid for the complete call. |
b | const Controls & | Value supplied for b. 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 "instrument_synth.hpp"
// Assume these named values have been initialized with valid data:
// uint16_t source
// const Controls & a
// const Controls & b
auto result = epok::instrument::synth::detail::source_changed(source, a, b);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.
