Overview

C-level binding for OpenAL's "alc" API.

Please consider using the Go-level binding instead.

Note that "alc" introduces the exact same types as "al" but with different names. Check the documentation of openal/al for more information about the mapping to Go types.

XXX: Sadly we have to returns pointers for both Device and Context to avoid problems with implicit assignments in clients. It's sad because it makes the overhead a lot higher, each of those calls triggers an allocation.

Go binding for OpenAL's "al" API.

See http://connect.creativelabs.com/openal/Documentation/OpenAL%201.1%20Specification.htm for details about OpenAL not described here.

OpenAL types are (in principle) mapped to Go types as follows: 

ALboolean	bool	(al.h says char, but Go's bool should be compatible)
ALchar		uint8	(although al.h suggests int8, Go's uint8 (aka byte) seems better)
ALbyte		int8	(al.h says char, implying that char is signed)
ALubyte		uint8	(al.h says unsigned char)
ALshort		int16
ALushort	uint16
ALint		int32
ALuint		uint32
ALsizei		int32	(although that's strange, it's what OpenAL wants)
ALenum		int32	(although that's strange, it's what OpenAL wants)
ALfloat		float32
ALdouble	float64
ALvoid		not applicable (but see below)

We also stick to these (not mentioned explicitly in OpenAL): 

ALvoid*		unsafe.Pointer (but never exported)
ALchar*		string

Finally, in places where OpenAL expects pointers to C-style arrays, we use Go slices if appropriate: 

ALboolean*	[]bool
ALvoid*		[]byte (see Buffer.SetData() for example)
ALint*		[]int32
ALuint*		[]uint32 []Source []Buffer
ALfloat*	[]float32
ALdouble*	[]float64

Overall, the correspondence of types hopefully feels natural enough. Note that many of these types do not actually occur in the API.

The names of OpenAL constants follow the established Go conventions: instead of AL_FORMAT_MONO16 we use FormatMono16 for example.

Conversion to Go's camel case notation does however lead to name clashes between constants and functions. For example, AL_DISTANCE_MODEL becomes DistanceModel which collides with the OpenAL function of the same name used to set the current distance model. We have to rename either the constant or the function, and since the function name seems to be at fault (it's a setter but doesn't make that obvious), we rename the function.

In fact, we renamed plenty of functions, not just the ones where collisions with constants were the driving force. For example, instead of the Sourcef/GetSourcef abomination, we use Getf/Setf methods on a Source type. Everything should still be easily recognizable for OpenAL hackers, but this structure is a lot more sensible (and reveals that the OpenAL API is actually not such a bad design).

There are a few cases where constants would collide with the names of types we introduced here. Since the types serve a much more important function, we renamed the constants in those cases. For example AL_BUFFER would collide with the type Buffer so it's name is now Buffer_ instead. Not pretty, but in many cases you don't need the constants anyway as the functionality they represent is probably available through one of the convenience functions we introduced as well. For example consider the task of attaching a buffer to a source. In C, you'd say alSourcei(sid, AL_BUFFER, bid). In Go, you can say sid.Seti(Buffer_, bid) as well, but you probably want to say sid.SetBuffer(bid) instead.

TODO: Decide on the final API design; the current state has only specialized methods, none of the generic ones anymore; it exposes everything (except stuff we can't do) but I am not sure whether this is the right API for the level we operate on. Not yet anyway. Anyone?
