[Zlib-devel] vsnprintf (in gzio.c) And Microsoft Visual Studio 7 (.net)

[Gilles Vollant]

In Microsoft Visual Studio 7 (.net), there is no vsnprintf. There is
only :

_CRTIMP int __cdecl _vsnprintf(char *, size_t, const char *, va_list);

With a "_" before vsnprintf

We have two solution to  compile gzio.c

1)
#define NO_vsnprintf
OR
#define vsnprintf _vsnprintf



I've uploaded http://www.winimage.com/zLibDll/zconfgv.zip with
zconf120gv2.h (a new zconf.h) where I added

/*
 * Microsoft Visual C++ did not define vsnprintf but define _vsnprintf
 */
#ifdef _MSC_VER
#  define vsnprintf _vsnprintf
#endif
