They are typed as such (from cmds.h):

typedef int * (* mod_entry_t)(char **);

typedef int (* mod_entry_t)(char **);
typedef void (* mod_help_t)(unsigned int);

typedef void * (* builtin_help_t)(unsigned int);
typedef int (* builtin_entry_t)(char **, cliuser_t *);
typedef void (* builtin_help_t)(unsigned int);
 
As you can see, both modular and builtin commands expect an array of
arguments, however bulitins also expect to be pointed to cliuser_t.
153,9 → 153,7
 
2: Change your "usage()" command as shown:
-- void usage(...)
++ void * help_cmd_foo(unsigned int level)
-- return;
++ retrn CMD_VOID;
++ void help_cmd_foo(unsigned int level)
 
'level' is either 0 or 1, indicating the level of help requested.
If the help / usage function currently exits based on how it is
163,33 → 161,19
 
3: Change the programs "main()" as shown:
-- int main(int argc, char **argv)
++ int * cmd_foo(char **argv)
++ int cmd_foo(char **argv)
-- return 1;
++ return CMD_FAILURE;
-- return 0;
++ return CMD_SUCCESS;
 
If main() returns an int that is not 1 or 0 (e.g. 127), cast it as
such:
 
-- return 127;
++ return (int *) 127;
 
NOTE: _ONLY_ the main and help entry points need to return int * or
void *, respectively. Also take note that argc has changed. The type
for entry points may soon change.
 
NOTE: If main is void, you'll need to change it and ensure that its
expecting an array of arguments, even if they'll never be read or
used. I.e.:
 
-- void main(void)
++ int * cmd_foo(char **argv)
++ int cmd_foo(char **argv)
 
Similararly, do not try to return CMD_VOID within the modules main
entry point. If somehow you escape the compiler yelling at you, you
will surely see pretty blue and yellow fireworks once its reached.
 
4: Don't expose more than the entry and help points:
-- void my_function(int n)
++ static void my_function(int n)
