Well, yes -- but the function, what is it for?

Hi again, and thank you for the explanation... the function was to send to the treeWalker function the values that getopt sends instead, that is, the input for treeWalker ,
Code:
void dirTreeWalker(char fileType, char *dirName)

in other words I was trying to "set getopt", just like you said , instead of using it. As it is now it works fine just by using getopt instead of trying to set it as I was doing.

Code:
while ((c = getopt(argc, argv, options)) != -1) {
    switch(c) {
    case 't':
        printf("t is set\n");
        break;
        
    case 'd':
        printf("d is set\n");
        fileType = 'd';
        printf("filename is %c\n", fileType);
        break;
    case 'f':
        printf("f is set\n");
        fileType = 'f';
        printf("filename is %c\n", fileType);
        break;
/*and so on*/
