Source Files Modified source files setsdate.c use Win32 API functions instead of DOS interrupt setstime.c use Win32 API functions instead of DOS interrupt getsdate.c use Win32 API functions instead of DOS interrupt getstime.c use Win32 API functions instead of DOS interrupt arab2rom.c create wrapper function to return length of string so function is callable from Visual Basic and Delphi (* see Wrapper functions) dowabbr.c create wrapper function (see arab2rom.c) downame.c create wrapper function (see arab2rom.c) fmdtamdy.c create wrapper function (see arab2rom.c) fmdtaymd.c create wrapper function (see arab2rom.c) fmdtndmy.c create wrapper function (see arab2rom.c) fmdtmdmy.c create wrapper function (see arab2rom.c) fmdtnmdy.c create wrapper function (see arab2rom.c) fmdtnymd.c create wrapper function (see arab2rom.c) fmdtadmy.c create wrapper function (see arab2rom.c) fmttm24.c create wrapper function (see arab2rom.c) fmttm12.c create wrapper function (see arab2rom.c) monthmil.c create wrapper function (see arab2rom.c) monthnam.c create wrapper function (see arab2rom.c) scdtl_1.h Added #include to get definitions for WINAPI scdtl_2.h Added WINAPI to function headers for stdcall calling convention scdtl_3.h Added WINAPI to function headers for stdcall calling convention scdtl_5.h Added WINAPI to function headers for stdcall calling convention scdtl_7.h Added WINAPI to function headers for stdcall calling convention 3. Other Included Files scdtl.mdp Microsoft Visual C++ project file scdtl.lib C link library scdtl.dll Win32 Release DLL (statically linked to C runtime library) scdtld.dll Win32 Debug DLL (statically linked to C runtime library) scdtl.bas Microsoft Visual Basic module containing function declarations for SCDTL.DLL scdtl.pas Delphi module containing function declarations for SCDTL.DLL 4. Function Names for Visual Basic and Delphi The names of the functions have been changed in the BASIC module to be more like Visual Basic names. For example: Declare Function ArabicToRoman Lib "SCDTL" & _ Alias "arabic_to_roman_2" (ByVal n As Long, ByVal s As String) As Long The C function 'arabic_to_roman' is referenced as 'ArabicToRoman' in Visual Basic. See SCTDL for the Visual Basic function declarations. The function calls were tested with Visual Basic 5. The same naming convention was used for Delphi. See SCDTL.PAS for the Delphi function declarations. The function calls were tested with Delphi Version 2.0. 5. Wrapper Functions for Visual Basic and Delphi Certain functions did not make themselves easily callable from Visual Basic and Delphi. Rather than change the original function, a wrapper function was created. An example is month_name (referenced as MonthName from VB and Delphi). The C prototype for month_name is: char *month_name (int month_index); A wrapper was created so that a string was a parameter instead of a return value: int month_name_2 (int month_index, char *name); The return value is the length of the returned string. The Visual Basic and Delph declarations reference the month_name_2 function: Declare Function MonthName_2 Lib "SCDTL" & _ Alias "month_name_2" & _ (ByVal month_index As Long, ByVal month_name As String) As Long and have the following wrapper function return the month name string: Public Function MonthName(month_index As Long) As String Dim s As String s = String(10, vbNullChar) ' max of 10 chars including null terminator l = MonthName_2(month_index, s) s = Left(s, l) MonthName = s End Function The user of the function simply needs to call this function as described in the text: Dim monthName As String monthName = MonthName( MONTH_JANUARY ) 6. Calling SCDTL Functions from C and C++ The stdcall calling convention was used for the SCDTL DLL functions. The function prototypes have been modified to use the WINAPI calling convention. For example, the text describes the function month_name in the header file scdtl_2.h: extern char *month_name (int month_index); This has been changed to: extern char * WINAPI month_name (int month_index); to set the calling convention for the function. To use SCDTL.DLL simply include the appropriate header files (scdtl_1.h, etc.) in your source files and link to SCDTL.LIB. Microsoft Visual C++ 4.0 was used to create the DLL and LIB files. The SCDTL DLL was statically linked with the multithreaded runtime library.
