int split(char *text,char *x,char **output)
{
    int textlen,xlen,//后面初始化
        pointer=0,//"text"的偏移
        n=0;//output的个数
    textlen=strlen(text);
    xlen=strlen(x);
    
    while(1)
    {
        char *p, *t;
        p=strstr(text+pointer,x);
        if(NULL!=p)*p=0;
        t=(char *)malloc(sizeof(char)*strlen(text+pointer)+4);
        strcpy(t,text+pointer);
        output[n++]=t;
        pointer=p+xlen-text;
        if(NULL==p)break;
    }
    return n;
}
