NAME

fsmakedev − Create a device file

SYNOPSIS

fsmakedev [-s serverID] [-d devType] [-u unit] [-p mode] name

OPTIONS

−s serverIDThe serverID is needed for devices attached to a particular host.  If not specified then the device created is a common device found on all hosts and the local instance of the device is used.  The serverID is a numeric hostID, not a name. 

−d devTypeThis specifies the type of the device.  This is a numeric value found in /sprite/src/kernel/dev/∗.md/devTypesInt.h

−u unitThe unit number of the device. 

−p modeThis specifies the permission bits of the device file. 

nameThis is the name of the device. 
 

DESCRIPTION

Fsmakedev creates a special device file that is a placeholder for a peripheral device.  The device file indicates the device type and a unit number.  It also indicates the location of the device.  In Sprite devices are either common, which means that all hosts have them, or they are specific to a particular host.  When a common device is opened then the device attached to the local host is used.  Otherwise the serverID in the device file indicates where the device is.  The default is for a common device file to be created.  Use the -s option to specific the serverID for devices attached to a particular host.  By convention common devices are found in the /dev directory, and specific devices are in the /hosts/hostname/dev directory. 

BUGS

The device type is a magic number found in the /sprite/src/kernel/dev/∗.md/devTypesInt.h file.  The serverID is a numeric hostID, not a hostname.
