Using the return statement u can only return one value at a
time.
So you can either return the value of a variable like you
can return an integer, or you can return pointer (which may
contain more than one values), which is pointing to
dynamically allocated location, Like in given below example:
//Returning two values from a function.

#include "stdio.h"
#include "malloc.h"

int *values()
{
int *ptr;
ptr = (int*)malloc(2);
*ptr = 10;
*(ptr+1) = 20;
return ptr;
}

int main()
{
int *ptr = values();
printf("%d\n%d",*ptr,*(ptr+1));
return 0;
}

stripos — Find position of first occurrence of a case- insensitive string int stripos ( char* haystack, char* needle, int offset ) Returns the numeric position of the first occurrence of needle in the haystack string. Note that the needle may be a string of one or more characters. If needle is not found, stripos() will return -1. The function should not make use of any C library function calls.
