 mjs_set(mjs, g, "myfunc", ~0, mjs_mk_foreign(mjs,my_func));

See example in https://github.com/cesanta/mjs/blob/master/mjs.c, search for mjs_init_globals

from mjs.

thanks for your reply,this is my code ,but result is error:
`#include "mjs.h"

void foo(int x) {
printf("Hello %d!\n", x);
}

void *my_dlsym(void *handle, const char *name) {
//if (strcmp(name, "foo") == 0) return foo;
return NULL;
}

int main(void) {
struct mjs *mjs = mjs_create();
mjs_set_ffi_resolver(mjs, my_dlsym);
mjs_set(mjs,mjs_get_global(mjs), "foo", ~0, mjs_mk_foreign(mjs, foo));
//mjs_set(mjs, g, "myfunc", ~0, mjs_mk_foreign(mjs, my_func));
mjs_exec(mjs, " for(let i=0;i<10;++i) foo(1234);", NULL);
return 0;
}`
this is result:
Hello 2922240!
Hello 2922240!
Hello 2922240!
Hello 2922240!
Hello 2922240!

your function needs to take the parameter from the JS stack.
See the example I gave you, how those functions take parameters.

from mjs.
