byte routine not working

ok i am making a byte routine taht searches for a particular byte in a string of bytes. All the addresses of the found bytes are stored in an array. But its not working and i cant figure out why. Please tell me what i have done wrong:

Code:

---

char *cptr = strchr(bytebuffy, searchnum);

                                        while(cptr != NULL)
                                        {
                                                int a = cptr - bytebuffy;
                                                Addresses1[g_FoundCount + 1] = readbase + a;
                                                g_FoundCount++;
                                                       
                                                cptr = strchr(bytebuffy + a, searchnum);
                                        }

---

when this runs the windows program just hangs and stops responding as if the while loop wont stop looping :(

> int a = cptr - bytebuffy
And if this is 0, then

> cptr = strchr(bytebuffy + a, searchnum);
Is going to give you the same answer as last time

Restart your search from the character after the one you've just found.

It would be easier to do this using the string class.

Change this line:

Code:

---

cptr = strchr(bytebuffy + a, searchnum);

---

to

Code:

---

cptr = strchr(bytebuffy + a + 1, searchnum);
