# KCalc: simple kernel calculator module

## Usage

    echo "1 + 1" > /dev/kcalc

    cat /dev/kcalc

`write` the pseudo /dev/kcalc device with the expression, then you can get result simply with counterpart system call `read`.

## TODO

* Read/Write lock

* Permission FIX

* Blocked read

* Larger tests
