def add_function(name : String, return_type : String, args : FieldArray | Nil = nil) : self #

Adds a C function (name, return type, and optional arguments).

libc_type = Crygen::Types::LibC.new("C")
libc_type.add_function("getch", "Int32", [{"arg1", "Int32"}, {"arg2", "Int32"}])

Output:

lib C
  fun getch(arg1 : Int32, arg2 : Int32) : Int32
end

def add_struct(name : String, fields : FieldArray) : self #

libc_type = Crygen::Types::LibC.new("C")
libc_type.add_struct("Person", [{"name", "String"}, {"age", "Int32"}])

Output:

lib C
  struct Person
    name : String
    age : Int32
  end
