const CharType *_Narrow_s(
const CharType *first,
const CharType *last,
A pointer to the first character in the range of characters to be converted.
A pointer to the character immediately following the last character in the range of characters to be converted.
The default value to be assigned by the member function to characters of type CharType that do not have counterpart characters of type char.
A const pointer to the first character of type char in the destination range that stores the converted range of characters.
The size of dest in bytes.
This member function returns a pointer to the destination range of native characters converted from characters of type CharType.
This member function returns _Do_narrow_s(first, last, default, dest, dest_size).
