		24	DESCRIPTION
		25	<> converts the error number <[errnum]> into a
		26	string. The value of <[errnum]> is usually a copy of <>.

		28	empty string.

		291	RETURNS
		292	This function returns a pointer to a string. Your application must
		293	not modify that string.
		294
		295	PORTABILITY
		296	ANSI C requires <>, but does not specify the strings used
		297	for each error number.
		298
		299	Although this implementation of <> is reentrant, ANSI C
		300	declares that subsequent calls to <> may overwrite the
		301	result string; therefore portable code cannot depend on the reentrancy
		302	of this subroutine.
		303
		304	This implementation of <> provides for user-defined
		305	extensibility. <> defines <[__ELASTERROR]>, which can be
		306	used as a base for user-defined error values. If the user supplies a
		307	routine named <<_user_strerror>>, and <[errnum]> passed to
		308	<> does not match any of the supported values,
		309	<<_user_strerror>> is called with <[errnum]> as its argument.
		310
		311	<<_user_strerror>> takes one argument of type <[int]>, and returns a
		312	character pointer. If <[errnum]> is unknown to <<_user_strerror>>,
		313	<<_user_strerror>> returns <[NULL]>. The default <<_user_strerror>>
		314	returns <[NULL]> for all input values.
		315
		316	<> requires no supporting OS subroutines.
