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.
