|
|
commands and functions
|
|
each function is responsible for decoding a command
|
|
all function names are in the form cmd_xxxx() (for a basic command) or fun_xxxx() (for a basic function) so, if you want to search for the
|
|
function responsible for the NAME command look for cmd_name
|
|
|
|
There are 4 items of information that are setup before the command is run.
|
|
All these are globals.
|
|
|
|
int cmdtoken This is the token number of the command (some commands can handle multiple
|
|
statement types and this helps them differentiate)
|
|
|
|
char *cmdline This is the command line terminated with a zero char and trimmed of leading
|
|
spaces. It may exist anywhere in memory (or even ROM).
|
|
|
|
char *nextstmt This is a pointer to the next statement to be executed. The only thing a
|
|
command can do with it is save it or change it to some other location.
|
|
|
|
char *CurrentLinePtr This is read only and is set to NULL if the command is in immediate mode.
|
|
|
|
The only actions a command can do to change the program flow is to change nextstmt or
|
|
execute longjmp(mark, 1) if it wants to abort the program.
