Get an Array of Strings Between Two Strings in C - c

Question

I'm looking for a very simple way to return an array of strings that are contained between trailing and leading strings. Here's an example:
char *text = ;;;Text I want]]] Text I don't care about ;;;More Text I want]]] More text I don't care about
Calling stringBetweenString(";;;","]]]",text) should return an array (const char *myArray[2]) with the following values: "Text I want","More Text I want".
Unfortunately, I do not have access to RegEx for this application, nor external libraries. Any help would be greatly appreciated, thanks!

There is no need for a regex, as others have noted strstr will search within a string for the occurrence of a substring, returning a pointer to the beginning of the substring on success, NULL otherwise. You can use that with simple pointer arithmetic to parse the wanted text from between the substrings, e.g.:
#include <stdio.h>
#include <string.h>
#define MAXC 128
int main (void) {
char *text = ";;;Text I want]]] Text I don't care about ;;;More "
"Text I want]]] More text I don't care about";
char buf[MAXC] = "", *p = text, *ep;
while ((p = strstr (p, ";;;"))) {
if ((ep = strstr (p, "]]]"))) {
strncpy (buf, p + 3, ep - p - 3);
buf[ep - p - 3] = 0;
printf ("buf: '%s'\n", buf);
}
else
break;
p = ep;
}
return 0;
}
Example Use/Output
$ ./bin/splitbetween
buf: 'Text I want'
buf: 'More Text I want'
