rtapi_snprintf, rtapi_vsnprintf - Perform snprintf-like string formatting

       As for snprintf(3) or vsnprintf(3).

       These  functions  work  like  the  standard  C  printf functions, except that a reduced set of formatting
       operations are supported.

       In particular: formatting of long long values is not supported.  Formatting of floating-point  values  is
       done as though with %A even when other formats like %f are specified.
