You will not be able to compile this file correctly without gcc, because
|
|
it is necessary to pack the "wavefront_alias" structure to a size
|
|
of 22 bytes, corresponding to 16-bit alignment (as would have been
|
|
the case on the original platform, MS-DOS). If this is not done,
|
|
then WavePatch-format files cannot be read/written correctly.
|
|
The method used to do this here ("__attribute__((packed)") is
|
|
completely compiler dependent.
|
|
|
|
All other wavefront_* types end up aligned to 32 bit values and
|
|
still have the same (correct) size.

correctly parse *type* __attribute__ tags. It will do the

right thing if we use the "packed" attribute on each struct
|
|
member, which has the same semantics anyway.

Because most/all of the sample data we pass in via pointers has
|
|
never been copied (just mmap-ed into user space straight from the
|
|
disk), it would be nice to allow handling of multi-channel sample
|
|
data without forcing user-level extraction of the relevant bytes.
|
|
|
|
So, we need a way of specifying which channel to use (the WaveFront
|
|
only handles mono samples in a given slot), and the only way to do
|
|
this without using some struct other than wavefront_sample as the
|
|
interface is the awful hack of using the unused bits in a
|
|
wavefront_sample:
|
|
|
|
Val Meaning
|
|
--- -------
|
|
0 no channel selection (use channel 1, sample is MONO)
|
|
1 use first channel, and skip one
|
|
2 use second channel, and skip one
|
|
3 use third channel, and skip two
|
|
4 use fourth channel, skip three
|
|
5 use fifth channel, skip four
|
|
6 use six channel, skip five
|
|
|
|
|
|
This can handle up to 4 channels, and anyone downloading >4 channels
|
|
of sample data just to select one of them needs to find some tools
|
|
like sox ...
