These error semantics apply only to * AL errors, not to system errors such as memory access errors. * </p> * <p> * Several error generation conditions are implicit in the description of the various AL * commands. First, if a command that requires an enumerated value is passed a value * that is not one of those specified as allowable for that command, the error * AL_INVALID_ENUM results. This is the case even if the argument is a pointer to a * symbolic constant if that value is not allowable for the given command. This will * occur whether the value is allowable for other functions, or an invalid integer value. * </p> * <p> * Integer parameters that are used as names for AL objects such as Buffers and * Sources are checked for validity. If an invalid name parameter is specified in an AL * command, an AL_INVALID_NAME error will be generated, and the command is * ignored. * </p> * <p> * If a negative integer is provided where an argument of type sizei is specified, the * error AL_INVALID_VALUE results. The same error will result from attempts to set * integral and floating point values for attributes exceeding the legal range for these. * The specification does not guarantee that the implementation emits * AL_INVALID_VALUE if a NaN or Infinity value is passed in for a float or double * argument (as the specification does not enforce possibly expensive testing of * floating point values). * </p> * <p> * Commands can be invalid. For example, certain commands might not be applicable * to a given object. There are also illegal combinations of tokens and values as * arguments to a command. AL responds to any such illegal command with an * AL_INVALID_OPERATION error. * </p> * <p> * If memory is exhausted as a side effect of the execution of an AL command, either * on system level or by exhausting the allocated resources at AL's internal disposal, * the error AL_OUT_OF_MEMORY may be generated.
