linux下运行时更改进程名

以前代码在linux下可以达到更改进程名，windows上不能实现此功能。

#include <stdio.h>#include <string.h>int main(int argc, char **argv){    char buff[100];     memset(buff,0,sizeof(buff));     strncpy(buff, argv[0], sizeof(buff));     memset(argv[0],0,strlen(buff));     strncpy(argv[0], "Hello world", 7);     getchar();    return 0;}
