Prototype

char *strrev(char *s);

wchar_t *_wcsrev(wchar_t *s);

unsigned char *_mbsrev(unsigned char *s);

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;
 }
