如何编写延时功能？ [英] How to write a time delay function?
问题描述
您好，
我想写一个时间延迟功能，例如Timedelay（float time_lenth）{}。
执行时，会延迟一些秒只要time_lenth
表示。你能帮忙写一下这样的功能吗？

usleep（）是一种方法（而支持）。
usleep() is one way to do it ( whereas it is supported ).

#include< time.h>
void Timedelay（float time_lenth）
{
time_t start = time（NULL）;
time_t end;
do
{
end = time（NULL）;
} while（difftime（end，start）< time_lenth）;
}
（大概是''lenth''在世界某个地方很有意义。）

#include <time.h>
void Timedelay(float time_lenth)
{
time_t start = time(NULL);
time_t end;
do
{
end = time(NULL);
} while(difftime(end, start) < time_lenth);
}
(Presumably ''lenth'' is meaningful somewhere in the world.)
