gettimeofdaytest.c

这是linux下的基础C编程代码。都是已经调试成功的

#include <sys/time.h> 
#include <stdio.h>

main()
{
struct timeval tpstart;

float micro;
char timeBuf[64];
char buf[64];

gettimeofday(&tpstart,NULL);

micro=tpstart.tv_usec;
//snprintf(timeBuf, sizeof(timeBuf),"%f", micro);
//strncat(buf, timeBuf,6);
//printf("\n%s",timeBuf);
//printf("\n%s\n",buf);

  printf("%f\n",micro);
}
