#define NLMISC_CONVERT_VARGS( _dest,

+Value:

char _cstring[_size]; \
+va_list _args; \
+va_start (_args, _format); \
+int _res = vsnprintf (_cstring, _size-1, _format, _args); \
+if (_res == -1 || _res == _size-1) \
+{ \
+        _cstring[_size-1] = '\0'; \
+} \
+va_end (_args); \
+_dest = _cstring
This macro converts variable arguments into C string (zero terminated string). +

+This function takes care to avoid buffer overflow. +

+Example: 

        void MyFunction(const char *format, ...)
+        {
+                string str;
+                NLMISC_CONVERT_VARGS (str, format, NLMISC::MaxCStringSize);
+                // str contains the result of the conversion
+        }
+ *
+
+Parameters:
+ + + +
_dest  +string or char* that contains the result of the convertion
_format  +format of the string, it must be the last argument before the '...' + \param _size size of the buffer that will contain the C string
