DESCRIPTION
- -
- - These data structures and functions provide parsing of textual - control messages. -
- - Parsecmd treats the n bytes at p (which need not be NUL-terminated) - as a UTF string and splits it using tokenize (see getfields(3)). - It returns a Cmdbuf structure holding pointers to each field in - the message. -
- - Lookupcmd walks through the array ctab, which has ntab entries, - looking for the first Cmdtab that matches the parsed command. - (If the parsed command is empty, lookupcmd returns nil immediately.) - A Cmdtab matches the command if cmd is equal to cb−>f[0] or if - cmd is *. Once a matching Cmdtab has been - found, if narg is not zero, then the parsed command must have - exactly narg fields (including the command string itself). If - the command has the wrong number of arguments, lookupcmd returns - nil. Otherwise, it returns a pointer to the Cmdtab entry. If lookupcmd - does not find a matching command at all, it returns - nil. Whenever lookupcmd returns nil, it sets the system error - string. -
- - Respondcmderror resoponds to request r with an error of the form - ‘fmt: cmd,’ where fmt is the formatted string and cmd is a reconstruction - of the parsed command. Fmt is often simply %r .

EXAMPLES
- -
- - This interface is not used in any distributed 9P servers. It was - lifted from the Plan 9 kernel. Almost any Plan 9 kernel driver - (/sys/src/9/*/dev*.c on Plan 9) is a good example.
