Thread: How to verify my incoming UDP packet correctly?

Code:

int compare(const char *string1, const char *string2) {
    return strcmp(string1, string2) == 0;
}

(I also added "const" to the parameters which you forgot to do.)

I checked how to use strcat, but here also, I'm not sure how to read the PacketBuffer, I just want to verify if the 3 digits of the string that is received on the UDP packet are the same as tableID;

Code:

if (packetBuffer, strcat(str1, str2)

Structure:
I've rewinded my code back to basic, thought it was helpful to share a bit more code.
