Question

I’m looking for RTL delphi function equivalent to the sscanf/swscanf C++ functions. Exist something like that in the RTL delphi functions or I must look for a third-party implementation?

Answer 1

I personally would simply call the real functions which can be imported from msvcrt.dll.

function sscanf(buffer, format: PAnsiChar): Integer; 
    cdecl; varargs; external 'msvcrt.dll';
function swscanf(buffer, format: PWideChar): Integer; 
    cdecl; varargs; external 'msvcrt.dll';

These are tried and tested robust implementations of the C standard library functions.
