Hello out there !
I am new to learn C for my own practice.
I have 2 books which I am studying and I have copied some tutorials about my
GNU C Compiler
and also some informations about language C/C++.
So one of the urgent problem is, how to use functions mentioned in the
diverse lib's of the GNU C-Compiler

For example:
To use the 'getch'/'putch' Command was easy to understand and to learn,
because good described in literature.
But GNU C has so various and many other functions in its libs and by reading
the include-files and do not really know how
to take correct use of them.

Next example:
To take use of the function 'clrscr()' it took me about one day until I had
an "AHA-event" ->  I rememered that 10 years ago beeing busy with my 1st PC
on MS-DOS 2.0 I had to add the file ANSI.SYS to the config.sys in my system.
So after doing this now, the clrscr() really worked!

But there are hundreds of informations in the include-files what I do not
understand !!

Is there a way to have a introduction to my problem ?
Can anyone understand my pain ? I am sure that if I understand a few more
functions I am in the way to solve somemore problems in my own way without
help from outside.

Thanks in advance.
Be so kind to post answers not only in this newsgroup but also to my e-mail:
