It writes a sequence of characters to the standard error* stream as follows:  first (if <__s> is not a null pointer and the character* pointed to by <__s> is not the null character), the string pointed to by* <__s> followed by a colon (:) and a space; then an appropriate error* message string followed by a new-line character.  The contents of the* error message strings are the same as those returned by strerror() with* the argument `errno'.* * INCLUDE FILES: stdio.h ** RETURNS: N/A** SEE ALSO: strerror()*/void perror     (    const char *  __s	/* error string */    )    {    if ((__s) && (*__s != EOS))    	fprintf (stderr, "%s: ", __s);    fprintf (stderr, "%s\n", strerror (errno));    }
