    Post Help me solve compiling warnings?

    Hello, i recently updated my WSL program and when compiling the same program i get a ton of warnings. like...

    track.c:309:21: note: ‘snprintf’ output between 26 and 4121 bytes into a destination of size 4096 309 |
    snprintf( buf, MAX_STRING_LENGTH, "Don't make me find you, %s!", victname );

    my main file has these settings:

    #define MAX_KEY_HASH 2048
    #define MAX_STRING_LENGTH 4096 /* buf */
    #define MAX_INPUT_LENGTH 1024 /* arg */
    #define MAX_INBUF_SIZE 1024

    I tried rising the values but the problem persists.
    How i can fix it?
    Can anyone help?

    Try making MAX_STRING_LENGTH at least 4121

    Or make your 'victname' array a more realistic shorter length.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
