一个windows下取进程内存的代码

先保存一下,以免以后用到又要重写

1 #include <windows.h>
2 #include <stdio.h>
3 #include <stdlib.h>
4 #include <time.h>
5 #include "psapi.h"

if (NULL == hProcess)
{
fprintf(stderr, "pid: %d not exist.\n", pid);
return -1;
}

setvbuf(stdout, NULL, _IONBF, 0);
while(1)
{

struct tm* nowtime = localtime(&t);
#if 1

}

exit(-1);
}
