oleg,
- you have a C main app,
yes.
- define function sum (of int array returning int scalar)
yes.
and pass it to J
yes.
- form int array and pass it to J
nope...
after i register sum with j, i go into a REPL,
just like jconsole. here's my comments on my
main():
{cd(jsj("",0)); initialize
sfn("sum",(J(*)(void))sum,1); register sum
{C b[99];while(gets(b)) while read a line into b
{J r=jsj(b,0); execute the line
if(Nt==r->t&&NULL!=r->d) if error
eO("! %s\n",r->d); print error
else else
show(r); show result
cd(r); decrement ref count on result
}}}
the first thing i would try in the REPL
is "sum i.4"
