Node:Modifying the Startup Sequence, Previous:Running Image Files, Up:Image Files
You can add your own initialization to the startup sequence through the
'cold is invoked just before the
image-specific command line processing (i.e., loading files and
-e) strings) starts.
A sequence for adding your initialization usually looks like this:
:noname Defers 'cold \ do other initialization stuff (e.g., rehashing wordlists) ... \ your stuff ; IS 'cold
You can make a turnkey image by letting
'cold execute a word
(your turnkey application) that never returns; instead, it exits Gforth
You can access the (image-specific) command-line arguments through the
arg provides convenient
'cold exits normally, Gforth processes the command-line
arguments as files to be loaded and strings to be evaluated. Therefore,
'cold should remove the arguments it has used in this case.
'cold-- gforth ``tick-cold''
argc-- addr gforth ``argc''
Variable- the number of command-line arguments (including the command name).
argv-- addr gforth ``argv''
Variable- a pointer to a vector of pointers to the command-line arguments (including the command-name). Each argument is represented as a C-style string.
Return the string for the nth command-line argument.
