Ok, I've tried to put something together from the tutorials on the web
and ended up using this, which works:
char *c = argv[2];
for (c == argv[argc - 2]; *c != '\0'; c++)
if ((islower(*c)) || (isspace(*c)) || (ispunct(*c)))
{
printf("\nWrong characters in parameter!\n");
return EXIT_FAILURE;
}
However, it conflicts with my other conditions for the command line,
namely this:
if (argc == 2 && strcmp("-h", argv[1]) == 0)
{
return help();
}
It somehow doesn't like that the second parameter is not there. Under
linux, I get the error 'Segmentation fault: 11 (core dumped)'.
Any ideas?
