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.
