sl@0	19	* FUNCTION
sl@0	20	* <<strerror>>---convert error number to string

sl@0	22	* strerror
sl@0	23	* ANSI_SYNOPSIS
sl@0	24	* #include <string.h>
sl@0	25	* char *strerror(int <[errnum]>);
sl@0	26	* TRAD_SYNOPSIS
sl@0	27	* #include <string.h>
sl@0	28	* char *strerror(<[errnum]>)
sl@0	29	* int <[errnum]>;
sl@0	30	* <<strerror>> converts the error number <[errnum]> into a
sl@0	31	* string. The value of <[errnum]> is usually a copy of <<errno>>.
sl@0	32	* If <<errnum>> is not a known error number, the result points to an
sl@0	33	* empty string.
sl@0	34	* RETURNS
sl@0	35	* This function returns a pointer to a string. Your application must
sl@0	36	* not modify that string.
sl@0	37	* PORTABILITY
sl@0	38	* ANSI C requires <<strerror>>, but does not specify the strings used
sl@0	39	* for each error number.
sl@0	40	* Although this implementation of <<strerror>> is reentrant, ANSI C
sl@0	41	* declares that subsequent calls to <<strerror>> may overwrite the
sl@0	42	* result string; therefore portable code cannot depend on the reentrancy
sl@0	43	* of this subroutine.
sl@0	44	* <<strerror>> requires no supporting OS subroutines.
