#define NLMISC_CONVERT_VARGS (  _dest, _format, _size   )

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 '...' _size  size of the buffer that will contain the C string Definition at line 70 of file string_common.h.
