-** Description:	Localizable error code to string function.
-**
-**
-** NSPR provides a mechanism for converting an error code to a
-** descriptive string, in a caller-specified language.
-**
-** Error codes themselves are 32 bit (signed) integers.  Typically,
-** the high order 24 bits are an identifier of which error table the
-** error code is from, and the low order 8 bits are a sequential error
-** number within the table.  NSPR supports error tables whose first
-** error code is not a multiple of 256, such error code assignments
-** should be avoided when possible.
-**
-** Error table 0 is defined to match the UNIX system call error table
-** (sys_errlist); this allows errno values to be used directly in the
-** library.  Other error table numbers are typically formed by
-** compacting together the first four characters of the error table
-** name.  The mapping between characters in the name and numeric
-** values in the error code are defined in a system-independent
-** fashion, so that two systems that can pass integral values between
-** them can reliably pass error codes without loss of meaning; this
-** should work even if the character sets used are not the
-** same. (However, if this is to be done, error table 0 should be
-** avoided, since the local system call error tables may differ.)
-**
-** Libraries defining error codes need only provide a table mapping
-** error code numbers to names and default English descriptions,
-** calling a routine to install the table, making it ``known'' to NSPR
-** library.  Once installed, a table may not be removed.  Any error
-** code the library generates can be converted to the corresponding
-** error message.  There is also a default format for error codes
-** accidentally returned before making the table known, which is of
-** the form "unknown code foo 32", where "foo" would be the name of
-** the table.
-**
-** Normally, the error code conversion routine only supports the
-** languages "i-default" and "en", returning the error-table-provided
-** English description for both languages.  The application may
-** provide a localization plugin, allowing support for additional
-** languages.
