内核中snprintf使用

#include <stdio.h>

int main()
{
   char  netnamebuffer[100];
   char* audioname = "i2s_format";
   
   
	#if 0
			snprintf(v4l2_dev->name, sizeof(v4l2_dev->name), "%s %s",
			dev->driver->name, dev_name(dev));
	#endif 
    //读取字符串并存储在 buffer 中
	// int snprintf(char*str,size_t size,const char*format,...);
	snprintf(netnamebuffer,100,"%s %s %s %s %s",audioname,audioname,audioname,audioname,audioname);
	printf("%s\n",netnamebuffer);
	
	return 0;
}
