However I'm having difficulty understanding the way the External functions (generate, init, restore) work. There are a few included but I just cannot get the hang of it. I am wanting to generate passwords that follow a particular pattern. This pattern would follow these rules: 1) The first character is an upper-case letter or number. 2) The following characters, until maxlength - 2 to maxlength, will be lowercase letters 3) Characters in position of maxlength-3 to maxlength will be numbers or 'special' characters like !, $, @, #, *, etc; the generator will try first with rules #1 and #2 and maxlength being the special characters or number, then it will try with maxlength-1 to maxlength (the last 2 characters) being special or number, to maxlength-2 to maxlength. Is this difficult to write? I do program in C. Some guidance or an example of something like this would help me greatly. Thank you!
