[英]Expression result unused
I got some codes and I'm trying to fix some compiling bugs: 我有一些代码,我正在尝试修复一些编译错误:
StkFrames& PRCRev :: tick( StkFrames& frames, unsigned int channel )
{
#if defined(_STK_DEBUG_)
if ( channel >= frames.channels() - 1 ) {
errorString_ << "PRCRev::tick(): channel and StkFrames arguments are incompatible!";
handleError( StkError::FUNCTION_ARGUMENT );
}
#endif
StkFloat *samples = &frames[channel];
unsigned int hop = frames.channels();
for ( unsigned int i=0; i<frames.frames(); i++, samples += hop ) {
*samples = tick( *samples );
*samples++; <<<<<<<<<--------- Expression result unused.
*samples = lastFrame_[1];
}
return frames;
}
I don't understand what the codes is trying to do. 我不明白这些代码正在尝试做什么。 The codes are huge and I fixed quite a few.
代码很大,我修复了很多。 But googling didn't work for this.
但是,谷歌搜索对此不起作用。
Any ideas? 有任何想法吗?
First, you do an increment (the line which actually gives you warning). 首先,您进行增量操作(实际上会向您发出警告的行)。
*samples++;
And then you assign to that variable something else, which makes previous action unused. 然后,您为该变量分配其他内容,从而使先前的操作未使用。
*samples = lastFrame_[1];
I recommend you to read this code inside 'for' loop more carefully. 我建议您更仔细地在“ for”循环中阅读此代码。 It doesn't look very logical.
看起来不太合逻辑。
