A simple example:

Code Select Expand

#include <stdlib.h>
//#include <zip.h>
#pragma comment(lib, "zip.lib")
//#include "zip_stdcall.h"
#define ZIP_DEFAULT_COMPRESSION_LEVEL 6
typedef struct zip_t zip_t;
extern struct zip_t __stdcall *zip_open(const char *zipname, int level, char mode);
extern int __stdcall zip_entry_open(struct zip_t *zip, const char *entryname);
extern int __stdcall zip_entry_fwrite(struct zip_t *zip, const char *filename);
extern int __stdcall zip_entry_close(struct zip_t *zip);
extern int __stdcall zip_close(struct zip_t *zip);

int __cdecl main(void)
{
struct zip_t *zip = zip_open("meta.zip", ZIP_DEFAULT_COMPRESSION_LEVEL, 'w');
{
    zip_entry_open(zip, "meta.xml");
    {
        zip_entry_fwrite(zip, "meta.xml");
    }
    zip_entry_close(zip);
}
zip_close(zip);
return 0;
}

Thanks Timo,Vortex,

Yes I had that one and several other changes similar to what I did for 3.0.2
It is creating a zip file that can be opened with both Windows Explorer and 7z.

However there is something amiss.  Both LibreOffice Calc and Excel complain of a corrupted zip, but both will 'repair' it and open with all the data intact.

So it seems like something not quite right in the header, or other housekeeping part.  Checking the actual zipped files from an 'old' version and in the new 3.1.1 version shows the files themselves are identical.

Maybe I'll just start over - But I'll try your work first 

Thanks,
John Z

Feature requests / Re: Enhanced editor suggestion...

Just a few notes:
1) Workspace files was added long after project files, limiting the available options.
2) All 169 (currently) sub-projects of Pelles C is in the same workspace file. Not the biggest project in the world, but not "small". Once all the projects are set up, it's mostly a matter of switching between "Debug" and "Release" builds, which is already available for a workspace.

As always, I guess it boils down to what you are used to and what you expect...

Assembly discussions / Message only window

Last post by Vortex - April 21, 2026, 08:58:33 PM

A message only window is a special window not visible ( no GUI interface ) and designed to send and receive messages. The code below creates a timer and deletes a file named test12345.txt before destroying itself after 3 seconds.

Hi Timo,

It look like that compiling new version is not so easy. A lot of warnings and error messages.

Bug reports / Re: Some fonts are missing fro...

Last post by Pelle - April 21, 2026, 06:26:10 PM

The filtering is supposed to exclude fonts not useful in the current locale. The problem is that for a (C) programming environment, it's hard to ignore the Latin alphabet.

So, ander_cc, changing filtering code in EnumFontFaceProc() from...

Code Select Expand

if ((dwFontType & TRUETYPE_FONTTYPE) != 0 &&
        (pntm->ntmFontSig.fsCsb[0] & pls->lsCsbSupported[0]) == 0 &&
        (pntm->ntmFontSig.fsCsb[1] & pls->lsCsbSupported[1]) == 0)
        return 1;  /* unwanted font, but keep enumerating */

...to this, should fix the problem... right?

Code Select Expand

    if ((dwFontType & TRUETYPE_FONTTYPE) != 0 &&

        (pntm->ntmFontSig.fsCsb[0] & FS_LATIN1) == 0 &&    /* <=== NEW */

        (pntm->ntmFontSig.fsCsb[0] & pls->lsCsbSupported[0]) == 0 &&
        (pntm->ntmFontSig.fsCsb[1] & pls->lsCsbSupported[1]) == 0)
        return 1;  /* unwanted font, but keep enumerating */
Not pretty, but I can't a better approach right now so this will have to do...

Has anyone gotten the newest release version 3.1.1 of Github-kuba miniz to build in Pelles C?

https://github.com/kuba--/zip

Has new features as well as 64bit capability.
