* Description:

* *** CAUTION!!! KEEP DOC CONSISTENT---if you change text of a message

* ***            here, change two places:

* ***            1) the leading doc section (alphabetized by macro)

* ***            2) the real text inside switch(errnum)

* FUNCTION

* <<strerror>>---convert error number to string

* INDEX

* strerror

* ANSI_SYNOPSIS

* #include <string.h>

* char *strerror(int <[errnum]>);

* TRAD_SYNOPSIS

* #include <string.h>

* char *strerror(<[errnum]>)

* int <[errnum]>;

* <<strerror>> converts the error number <[errnum]> into a

* string.  The value of <[errnum]> is usually a copy of <<errno>>.

* If <<errnum>> is not a known error number, the result points to an

* empty string.

* RETURNS

* This function returns a pointer to a string.  Your application must

* not modify that string.

* PORTABILITY

* ANSI C requires <<strerror>>, but does not specify the strings used

* for each error number.

* Although this implementation of <<strerror>> is reentrant, ANSI C

* declares that subsequent calls to <<strerror>> may overwrite the

* result string; therefore portable code cannot depend on the reentrancy

* of this subroutine.

* <<strerror>> requires no supporting OS subroutines.

* QUICKREF

* strerror ansi pure

*

Get pointer to error message string.

Returns a pointer to a string with the error message

corresponding to the errnum error number.

The returned pointer points to a statically allocated string. 

Further calls to this function will overwrite its content.
