HTTPMESSAGE_PRINTF_BUFFER

#define HTTPMESSAGE_PRINTF_BUFFER	(		_output,
			_output_size,
			...
	)

Value:

{ \
    int _result = snprintf (_output, _output_size, __VA_ARGS__); \
    if (_result < 0) return _result; \
    _output += (size_t)_result; _output_size -= (size_t)_result; \
}

Format a text and write it to a buffer. update I/O buffer pointer and length.

HTTPMESSAGE_PRINTF_FILE

#define HTTPMESSAGE_PRINTF_FILE	(		_written,
			_file,
			...
	)

Value:

{ \
    int _result = fprintf (_file, __VA_ARGS__); \
    if (_result < 0) return _result; \
    _written += (size_t)_result; \
}
