在C编程中使用pther线程printf时从线程进行多线程scanf

Question

对于我的游戏项目点，我使用多线程来显示用户经过的时间，但是在用户输入时，光标在完成输入之前会与用户输入重叠，因此我想在不影响用户输入的情况下将线程固定到控制台

What you need is something like this, which is in my notes taken from Linux System Programming book:

Manual File Locking

The function flockfile() waits until stream is no longer locked, bumps the lock count, and then acquires the lock, becoming the owning thread of the stream, and returns:

#include <stdio.h> void flockfile (FILE *stream);

The function funlockfile() decrements the lock count associated with stream:

#include <stdio.h>

void funlockfile (FILE *stream)

flockfile (stream);

fputs ("List of treasure:\n", stream);
fputs (" (1) 500 gold coins\n", stream);
fputs (" (2) Wonderfully ornate dishware\n", stream);

funlockfile (stream);

Hope that helps.
