NAME

       strrev - reverse a string in place

SYNOPSIS

       #include <publib.h>
       char *strrev(char *str);

DESCRIPTION

       strrev  reverses  the  argument string in place, i.e., it swaps the ith character from the beginning with
       the ith character from the end.

RETURN VALUE

       strrev returns its argument.

EXAMPLE

       Reversing "dlrow, elloh" would be done like the following.

            char str[] = "dlrow, elloh";

            puts(strrev(str));

       This would output "hello, world".  Note that using the string literal as the argument would be an  error,
       since it is not allowable to modify string literals.

BUGS

       Does not automatically detect palindromes, nor automatically return without doing anything.
