I did this

in ws.c there are several calls of infof() function. For curl_off_t variables %zu format is used which breaks the output. %llu format works well, at least here in Visual Studio 2022, win32 platform.

I expected the following

curl/libcurl version

curl 7.87.1-DEV (i386-pc-win32) libcurl/7.87.1-DEV Schannel WinIDN

operating system

Windows 11
Visual Strudio 2022

I believe %Ou is the correct one for our own printf implementation:

curl/lib/mprintf.c

Lines 360 to 366 in 12e9186

case 'O':
#if (SIZEOF_CURL_OFF_T > SIZEOF_LONG)
flags |= FLAGS_LONGLONG;
#else
flags |= FLAGS_LONG;
#endif
break;
