NAME

mdconfigconfigure MEMORY disks

SYNOPSIS

mdconfig special_file 512-byte-blocks

DESCRIPTION

The mdconfig command configures memory disk devices. It will associate the special file special_file with a range of user-virtual memory allocated by the mdconfig process itself. The mdconfig command should be run in the background. If successful, the command will not return. Otherwise, an error message will be printed.

To "unconfigure" the memory disk, just kill the background mdconfig process started earlier.

FILES

/dev/rmd??
/dev/md??

EXAMPLES

mdconfig /dev/md0c 2048 &

Configures the memory disk md0c with one megabyte of user-space memory.

BUGS

The special device will become inoperative if the mdconfig process is killed while the special device is open.
