Wrapper around kernel memory access.
<p>
It lets you read from and write to the kernel without taking care of offsets or file access.

Create the object with a fairly standard configuration.

This constructor will assume that you want to use /dev/mem and a standard offset (as used by any 2.4.x and any 2.2.x kernel not defined to use more than 1GB of ram). </td>

sets the file to use. This must be either PROCKCORE (to use /proc/kcore as the memory device) or DEVMEM (to use /dev/mem as the memory device). </td></tr>

</em> </td><td>
sets the offset from real memory addresses to virtual (kernel-) addresses. This is only needed if (file == DEVMEM), otherways supply IGNORE. </td></tr>
