 The APIs can handle (and format appropriately) any data of the following
 types: signed or unsigned integers, floating point numbers, booleans, strings
-(C-strings, std::strings, or std::string_views), sdbusplus enums, and pointers.

 The APIs also perform compile-time analysis of the arguments to give descriptive
 error messages for incorrect parameters or format flags.  Some examples are:
