# std.outbuffer

Boilerplate:

class OutBuffer;
  OutBuffer provides a way to build up an array of bytes out of raw data. It is useful for things like preparing an array of bytes to write out to a file. OutBuffer's byte order is the format native to the computer. To control the byte order (endianness), use a class derived from OutBuffer.
  ubyte[] toBytes();
    Convert to array of bytes.
  void reserve(uint nbytes);
    Preallocate nbytes more to the size of the internal buffer.
    This is a speed optimization, a good guess at the maximum size of the resulting buffer will improve performance by eliminating reallocations and copying.
  void write(const(ubyte)[] bytes);
  void write(ubyte b);
  void write(byte b);
  void write(char c);
  void write(ushort w);
  void write(short s);
  void write(wchar c);
  void write(uint w);
  void write(int i);
  void write(ulong l);
  void write(long l);
  void write(float f);
  void write(double f);
  void write(real f);
  void write(invariant(char)[] s);
  void write(OutBuffer buf);
    Append data to the internal buffer.
  void fill0(uint nbytes);
    Append nbytes of 0 to the internal buffer.
  void alignSize(uint alignsize);
    0-fill to align on power of 2 boundary.
  void align2();
    Optimize common special case alignSize(2)
  void align4();
    Optimize common special case alignSize(4)
  invariant(char)[] toString();
    Convert internal buffer to array of chars.
  void vprintf(invariant(char)[] format, void* args);
    Append output of C's vprintf() to internal buffer.
  void printf(invariant(char)[] format,...);
    Append output of C's printf() to internal buffer.
  void spread(uint index, uint nbytes);
    At offset index into buffer, create nbytes of space by shifting upwards all data past index.
