`ALRC' supports a very small number of primitives required to give the user a very small amount of control over OpenAL. Generally, the user can specific default values for things like listener position, source parameters, etc. Primitives are responsible for evaluation their own arguments, unlike expressions or functions. Therefore, an argument passed to a primitive may never be evaluated. The primitives are: `and' ( and predicate-1 predicate-2 ... ) Performs a logical `and' on parameters, using short circuit evaluation. Evaluates to true if none of the parameters evaluate to false. `or' ( or predicate-1 predicate-2 ... ) Performs a logical `or' on parameters, stopping at the first true evaluation. Evaluates to true if any of the parameters evaluate to true. `define' (define identifier value) `define' evaluates `value', and if `identifier' is not already in the symbol table, creates a new symbol named `identifier' with the evaluated `value'. If `identifier' is already defined, define sets it to the the evaluated `value'. `load-extension' ( load-extension "/absolute/pathname/plugin.so" ) `load-extension' informs openal of the presence of a plugin which conforms to the extension format described in Note: Making your own.
