### `bool pkpy_vectorcall(pkpy_vm*, int argc)`
|
|
|
|
Wraps `vm->vectorcall(argc)`. This function is used to call a function with a fixed number of arguments. The arguments are popped from the stack. The return value is pushed onto the stack.
|
|
|
|
1. First push the function to call.
|
|
2. Push `self` argument if it is a method call. Otherwise, call `pkpy_push_null`.
|
|
3. Push arguments from left to right.
|
|
|
|
!!!
|
|
Unlike lua, a python function always returns a value.
|
|
If the function returns `void`, it will push `None` onto the stack.
|
|
You can call `pkpy_pop_top` to discard the return value.
