Question

I have come across some legacy code that has the following type of line:

sscanf(szBuff,\"%Fd %Ff %Fd %Ff\"

Has anyone seeen a modifier like Fd or Ff? If so, wha

Answer 1

As ouah pointed out, these are the same as their lower case counterparts. Why is that? For symmetry with the printf conversion specifiers. Here %x and %X write lowercase or uppercase numbers like deadbeef and DEADBEEF. The symmetry allows to use the same format string for both input with scanf and output with printf.

#define FMT "%F\n"

sscanf (str, FMT, &value);
printf (FMT, value);
