Description

Reverses a string.

strrev changes all characters in a string to reverse order, except the terminating null character. (For example, it would change string\0 to gnirts\0.)

Return Value

strrev returns a pointer to the reversed string.

Example

#include <string.h>
#include <stdio.h>
int main(void)
{
   char *forward = "string";
   printf("Before strrev(): %s\n", forward);
   strrev(forward);
   printf("After strrev():  %s\n", forward);
   return 0;
}
