Member Function Documentation

◆ krk_buildGenerator()

KrkInstance * krk_buildGenerator ( KrkClosure function,
KrkValue arguments,
size_t  argCount 

Convert a function into a generator with the given arguments.

Converts the function function to a generator object and provides it arguments (of length argCount) as its initial arguments. The generator object is returned.

functionFunction to convert.
argumentsArguments to pass to the generator.
argCountNumber of arguments in arguments
A new generator object.

◆ krk_newClosure()

KrkClosure * krk_newClosure ( KrkCodeObject function,
KrkValue  globals 

Create a new function object.

Function objects are the callable first-class objects representing functions in managed code. Each function object has an associated code object, which may be sured with other function objects, such as when a function is used to create a closure.

functionCode object to assign to the new function object.
