Linux-wondershaper-usage

原本想用pyshaper來替代windows 的 netlimiter,

無奈說明文件太少加上不知道怎麼回事只要一啟動頻寬就自動變為0....

只好另謀策略,就找到wondershaper!

Coding-rewind-usage

rewind-將檔案指標指向一開始的位置

等同於

fseek ( stream , 0L , SEEK_SET );
=============================================

#include
#include

int main()
{
FILE *fp=fopen("/home/diousk/test/aaa","r+");
char str[20];
fscanf(fp,"%s",str);
printf("\nthe content is %s\n",str);
rewind(fp);
fprintf(fp,"%d",atoi(str)+1);
fclose(fp);

return 0;
}
