Detailed Description
Various handy helpers which std::string really should provide.

Macro Definition Documentation
◆ CONST_STRLEN
| #define CONST_STRLEN | ( | S | ) | (sizeof(S"") - 1) |
Returns the length of a string constant.
We rely on concatenation of string literals to produce an error if this macro is applied to something other than a string literal.

◆ STRINGIZE
| #define STRINGIZE | ( | X | ) | STRINGIZE_(X) |
The STRINGIZE macro converts its parameter into a string constant.

◆ STRINGIZE_
| #define STRINGIZE_ | ( | X | ) | #X |
