一、linux 中断API1.申请中断号request_irq(unsigned int irq,/*中断号*/irq_handler_t handler, /*中断处理函数*/unsigned long flags, /*中断标志*/const char *name,/*中断名称*/void *dev/*一般为设备结构体，dev会传递给中断处理函...

测试程序：// test.c#include <stdio.h>#include <pthread.h>int g_data = 0;void thread1_func(void *args){int i = 0;while(i < 2){i++;g_data += i;}}int main(){int i;int flag = 1;
