static会导致多线程的不安全问题吗？

[wllllll]

//设置A数据成B数据
static void StrInstal(char DaQuilt[], char DaPlan[]){
static char *HaQuilt,*HaPlan;
for ( HaQuilt = DaQuilt, HaPlan = DaPlan;
HaQuilt < DaQuilt + strlen(DaQuilt) && HaPlan < DaPlan + strlen(DaPlan);
HaQuilt++, HaPlan++
) *HaQuilt = *HaPlan;
if ( HaQuilt < DaQuilt + strlen(DaQuilt) ) *HaQuilt++ = 0;
}
//将数字转换为字符，并储存
static void ToString(int DaValue, char DaChar[]){
static char HaChar[32];
sprintf_s(HaChar, "%d", DaValue);
StrInstal(DaChar, HaChar);
}

会。需要加锁。

[do_fork]

线程同步时，volatile和锁是常常需要的

//设置A数据成B数据
static void StrInstal(char DaQuilt[], char DaPlan[]){
	char *HaQuilt,*HaPlan;
	for ( HaQuilt = DaQuilt, HaPlan = DaPlan;
		HaQuilt < DaQuilt + strlen(DaQuilt) && HaPlan < DaPlan + strlen(DaPlan);
		HaQuilt++, HaPlan++
	) *HaQuilt = *HaPlan;
	if ( HaQuilt < DaQuilt + strlen(DaQuilt) ) *HaQuilt++ = 0;
}
//将数字转换为字符，并储存
static void ToString(int DaValue, char DaChar[]){ 
	char HaChar[32];
	sprintf_s(HaChar, "%d", DaValue);
	StrInstal(DaChar, HaChar);
}

static静太方法并不会影响内部变量，对吧
