函数原型：

复制代码 代码如下:

size_t strftime (char* ptr, size_t maxsize, const char* format,const struct tm* timeptr );

代码示例：

复制代码 代码如下:

#include <stdio.h>

#include <time.h>

int main ()

{

time_t rawtime;

struct tm * timeinfo;

char buffer [128];

time (&rawtime);

timeinfo = localtime (&rawtime);

strftime (buffer,sizeof(buffer),"Now is %Y/%m/%d %H:%M:%S",timeinfo);

puts (buffer);

return 0;

}
