从字符串中提取数据，使用sscanf一直不对。。。

[qq_33576705]

代码如下，之前没用过这个提取子串的函数，刚学，照着网上的写法来写的，结果不对，谁帮忙看看，谢谢。。

			printf("devDetail->DevicePath: %s \n",devDetail->DevicePath);
			//结果 ==》    \\?\hid#vid_0483&pid_5750#7&2a6489c3&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}

			int vid,pid,num,addr,index,id;
			sscanf(devDetail->DevicePath,"%*[^#]#vid_%x&pid_%x#%d#%x&%d%&%d#%s",vid,pid,num,addr,index,id);
			printf(" vid = %x,pid = %x,num = %d,addr = %x,index = %d,id = %d \n",vid,pid,num,addr,index,id);

//k,v,n=-1,4,2
//End.

谢了 明白了
