globalvariable_receive_5  啥玩意?

void receive_comset( TypeDef_COM *fp_com)
{    fp_com=(TypeDef_COM *)&globalvariable_receive_5;
    fp_com->verification=globalvariable_receive_5[2];
    fp_com->data_bit=globalvariable_receive_5[3];
    fp_com->stop_bit=globalvariable_receive_5[4];
    fp_com->baud_rate[0]=globalvariable_receive_5[5];
    fp_com->baud_rate[1]=globalvariable_receive_5[6];
    fp_com->baud_rate[2]=globalvariable_receive_5[7];
    fp_com->end_status=globalvariable_receive_5[8];
}

是个数组  这样不行么？

fp_com=(TypeDef_COM *)&globalvariable_receive_5; //想问一下,你想干什么?globalvariable_receive_5是常量还是变量?
