hello,
I know how to use gh_new_procedure* functions to declare function
visible in scheme script.
But I want to declare many functions in a loop. I have a table of names
and a table of C-functions [ mytype_t function(my_type arg) ] and only
ONE C-function that converts SCM to mytype_t. It is a wrapper.
I would like to do it this way:
typedef struct
{
mytype_t (*func)(mytype_t arg);
char *name;
} scm_func_t;
scm_func_t FuncTable[50]; /* Initialized */
SCM wrapper(SCM arg, void *data) /* !!! watch "data" */
{
scm_func_t *sf = (scm_func_t *)data;
my_type_t my_result;
...
my_arg = SCM2my(arg);
...
my_result = sf->func(my_arg)
...
return my2SCM(my_result);
}
void declare_all_functions()
{
int i;
for (i=0; i<50; i++)
gh_new_procedure_data(FuncTable[i].func, &FuncTable[i]);
}
Do you feel the sense?
FuncTable can't be a table with "SCM (*)(SCM)" functions, because my
program uses few script languages in plugins.
