Short: AmigaOS 4: simple 4 unit ram device source Author: Olaf Barthel, Fredrik Wikstrom (OS4 port and modifications) Uploader: fredrik a500 org (Fredrik Wikstrom) Type: dev/src Version: 51.1 Architecture: generic /************************************************************************ * * ramdev.c -- Skeleton device code. * * A sample 4 unit ramdisk that can be bound to an expansion slot device, * or used without. Works with the Fast File System. * This code is required reading for device driver writers. It contains * information not found elsewhere. * * This example includes a task, though a task is not actually needed for * a simple ram disk. Unlike a single set of hardware registers that * may need to be shared by multiple tasks, ram can be freely shared. * This example does not show arbitration of hardware resources. * ************************************************************************/ v51.1 changes (Fredrik Wikstrom): - is now an OS4 device - uses CreateTask()/DeleteTask() as opposed to setting up the Task structure (stack, etc.) manually - supports the NSCMD_DEVICEQUERY command (reports itself as a trackdisk type device) Hopefully this will make it easier for people to write device drivers for OS4...
