You must write it. It is not difficult. Example:

#include <stdio.h>
#include <string.h>

unsigned int countSubStrings(char *data, char *find)
{
 unsigned int count = 0;
 char *p = data;
 while((p = strstr(p,find)) != NULL) {
  count++;
  p++;
 }
 return count;
}

int main()
{
 char *test = "This is a test of a substring search algorithm.";
 char *find = "i"; /* may be multi-character */
 printf("%u occurrences of \"%s\" in
\"%s\".\n",countSubStrings(test,find),find,test);
 return 0;
}
