You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: exceptions.go
    path of file: ./repos/go-python
    
    the code of the file until where you have to start completion: package python

// #include "go-python.h"
import "C"

import (
	"unsafe"
)

// void PyErr_PrintEx(int set_sys_last_vars)
// Print a standard traceback to sys.stderr and clear the error indicator. Call this function only when the error indicator is set. (Otherwise it will cause 
    
func PyErr_WarnExplicit(category *PyObject, message, filename string, lineno int, module string, registry *PyObject) error {
	c_message := C.CString(message)
	defer C.free(unsafe.Pointer(c_message))

	c_filename := C.CString(filename)
	defer C.free(unsafe.Pointer(c_filename))

	c_module := C.CString(module)
	defer C.free(unsafe.Pointer(c_module))

	return int2err(C.PyErr_WarnExplicit(topy(category), c_message, c_filename,
		C.int(lineno), c_module, topy(registry)))
}
