When I try to pass a C.int from package main to a function in a helper package called common, I get the following error:

main.go:24: cannot use argc (type C.int) as type common.C.int in argument to common.GoStrings

From common.go:

import "C"


func GoStrings(argc C.int, argv **C.char) (args []string) {
    // do stuff

From main.go:

#cgo LDFLAGS: -lpam -fPIC
#define PAM_SM_AUTH

#include <security/pam_appl.h>
import "C"


func pam_sm_authenticate(pamh *C.pam_handle_t, flags, argc C.int, argv **C.char) C.int {
    args := common.GoStrings(argc, argv)

Is there any way to pass these objects back and forth? I've tried type casting to e.g. common.C.int, but that doesn't seem to be valid syntax. I'd like to be able to call GoStrings from multiple different main programs, and it seems like that should be allowable.
