If the l modifier is used, the argument is first converted to a character string as if by %ls with a wchar_t[2] argument. N/A N/A int wint_t N/A N/A N/A N/A N/A s Writes a character string. The argument must be a pointer to the initial element of an array ...
宁以pass-by-reference-to-const 替换 pass-by-value (前者通常更高效、避免切割问题(slicing problem),但不适用于内置类型、STL迭代器、函数对象) 必须返回对象时,别妄想返回其 reference(绝不返回 pointer 或 reference 指向一个 local stack 对象,或返回 reference 指向一个 heap-allocated 对象,或返回 pointer ...

The signature of functions, which expect a string by value, isn't changed any more. Before,Delphi2Cpphad changed the code to pass a constant reference of the string instead. This is more efficient in C++, since it avoids copying the character array, but a manual post-processing of the co...
