String,String[] question when interop with tinyfiledialogs

[LukyGuyLucky]

I attached the program package here(as I can't upload zip file in discourse) for easy reference.
At this moment,there are 2 issues I am seeking help.It is about string/char* or it is about memory management which is exactly what I would like to learn always. :)

1. The program will crash if changing "Please input some text" to asian character

tinyfiledialogs::tinyfd_inputBox("query","Please input some text:","Input box");

2. The tinyfd_openFileDialog() will crash if not properly handling String[] conversion to char**

char* fileName=tinyfiledialogs::tinyfd_openFileDialog("let us read the password","../",2,
null,/(ZString)lFilterPatterns.ptr*///the latter will crash
"textfiles",1);
if (!fileName)
{
tinyfiledialogs::tinyfd_messageBox(
"Error",
"Open file name is NULL",
"ok",
"error",
0);
return ;
}

Thanks in advance,
Peter

I would expect tinyfiledialogs.lib to be placed in a directory called windows-x64 inside of the .c3l. This is usually were such files are expected to be.

These are wrong

extern fn char * tinyfd_utf8toMbcs(char  * aUtf8string);
extern fn char * tinyfd_utf16toMbcs(CUInt  * aUtf16string);//CUInt
extern fn CUInt * tinyfd_mbcsTo16(char  * aMbcsString);//CUInt
extern fn char * tinyfd_mbcsTo8(char  * aMbcsString);
extern fn CUInt * tinyfd_utf8to16(char  * aUtf8string);
extern fn char * tinyfd_utf16to8(CUInt  * aUtf16string);//CUInt

wchar_t should be replaced by Char16, not CUInt. wchar_t can be replaced by WString and char* by ZString:

extern fn char* tinyfd_utf8toMbcs(ZString aUtf8string);
extern fn char * tinyfd_utf16toMbcs(WString aUtf16string);
extern fn WString tinyfd_mbcsTo16(char* aMbcsString);
extern fn ZString tinyfd_mbcsTo8(char* aMbcsString);
extern fn WString tinyfd_utf8to16(ZString aUtf8string);
extern fn ZString tinyfd_utf16to8(WString aUtf16string);

char[] in C is basically the same as char*, but in C3 char[] is a slice.

Finally the question is what the functions expect. An Mbcs string? Strings from the source files will be UTF8.

extern char tinyfd_needs[]; /* info about requirements */

Must be

extern char** tinyfd_needs;

In C3.

For this

//Windows only section
//#ifdef _WIN32

The simplest solution is to start a new module section which is only visible on Windows:

//Windows only section
module tinyfiledialogs @if(env::WIN32);

Again all windows functions are incorrect as they use CUInt instead of Char16 (which is an ushort).

Thanks a lot.I am studying this.
