Direct translation:
const
TAG_FIELD_FLAG_DATA_TYPE_MASK = 6;
TAG_FIELD_FLAG_DATA_TYPE_TEXT_UTF8 = 0 shl 1;
TAG_FIELD_FLAG_DATA_TYPE_BINARY= 1 shl 1;
TAG_FIELD_FLAG_DATA_TYPE_EXTERNAL_INFO = 2 shl 1;
TAG_FIELD_FLAG_DATA_TYPE_RESERVED = 3 shl 1;

Just to clarify this a bit...
An audio file tag format uses 4 bytes to store a flag to indicate whether
text or binary information is stored in the following tag. The C++ source
code uses these definitions
#define TAG_FIELD_FLAG_DATA_TYPE_MASK (6)
#define TAG_FIELD_FLAG_DATA_TYPE_TEXT_UTF8 (0 << 1)
#define TAG_FIELD_FLAG_DATA_TYPE_BINARY (1 << 1)
#define TAG_FIELD_FLAG_DATA_TYPE_EXTERNAL_INFO (2 << 1)
#define TAG_FIELD_FLAG_DATA_TYPE_RESERVED (3 << 1)
Am I correct in assuming that a Binary flag will appear like this in the
file (in Hex).
00 00 00 02
Effectively a big endian value of 02. Is this correct?
Thanks,
Ross.

> So TAG_FIELD_FLAG_DATA_TYPE is a one-bit flag stored in the
2nd-rightmost bit of the word, and its possible values are TEXT_UTF8 (value
0) and BINARY (value 1).
I see. Thanks for that.
Cheers,
Ross.

That's the bitwise shift-left operator. So, 0 shifted left 1 bit is
still zero, 1 shifted left 1 bit is 2. 1 shifted left 30 bits would be (hex)
40000000.
