/**
* The AL detects only a subset of those conditions that could be considered errors.
* This is because in many cases error checking would adversely impact the

* <p>
* Each detectable error is assigned a numeric
* code. When an error is detected by AL, a flag is set and the error code is recorded.
* Further errors, if they occur, do not affect this recorded code. When GetError is
* called, the code is returned and the flag is cleared, so that a further error will again
* record its code. If a call to GetError returns AL_NO_ERROR then there has been no
* detectable error since the last call to GetError (or since the AL was initialized).
* </p>
* <p>
* Error codes can be mapped to strings. The GetString function returns a pointer to a
* constant (literal) string that is identical to the identifier used for the enumeration
* value, as defined in the specification.
* </p>
* <p>
* AL_NO_ERROR - "No Error" token.<br>
* AL_INVALID_NAME - Invalid Name parameter.<br>
* AL_INVALID_ENUM - Invalid parameter.<br>
* AL_INVALID_VALUE - Invalid enum parameter value.<br>
* AL_INVALID_OPERATION - Illegal call.<br>
* AL_OUT_OF_MEMORY - Unable to allocate memory.<br>
* </p>
* <p>
* The table summarizes the AL errors. Currently, when an error flag is set, results of
* AL operations are undefined only if AL_OUT_OF_MEMORY has occured. In other
* cases, the command generating the error is ignored so that it has no effect on AL
* state or output buffer contents. If the error generating command returns a value, it
* returns zero. If the generating command modifies values through a pointer
* argument, no change is made to these values. 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. This can also happen independent
* of recent commands if AL has to request memory for an internal task and fails to
* allocate the required memory from the operating system.
* </p>
* <p>
* Otherwise errors are generated only for conditions that are explicitely described in
* this specification.
