CvMat* nextimg = 0;
int firstframe;
firstframe=nextimg==0;
如果我不输入“== 0”,则会返回以下警告:
[Warning] assignment makes integer from pointer without a cast
最佳答案
它缩短了相当于
int firstframe;
if (nextimg == 0) {
firstframe = 1;
}
else {
firstframe = 0;
}
关于c - C语言的Opencv库。这条指令到底是什么int = pointer == 0; ?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/14441969/
