Stat(); test for the S_IFDIR bit set in st_mode. See the manual pages
for stat and the mknod function (in section 2 - not the mknod utility in
section 1).

Hey Now Rupert,

Thanks for the stat function. U referred to section 1 & 2. What book is
this?

Thanks

Hi Danny,

It's not a book, it's the man(ual) pages you get on most Unix system.

To get the documentation for a program or library function, if the people 
who provided those also provided the man pages, you can usually simply type 
from the prompt

man name_of_the_function

The man pages are divided in sections, one for user programs, one for 
system programs, one for C library routines, one for games, etc...
If a keyword is used in more than one section, you can chose which section 
to search specifying te number on the command line, like

man 2 name_of_the_function

Hope this helps,
fwyzard

directories for newbies

[danny]

Hey Now Gcc People,

I'm an old borland dos dude. For directory listing I'm used to findfirst
and findnext. I was looking around the gcc site for linux instructions
but could not find any. I bet there right under my nose but I don't
c'em. Basically I wish for an interactive web page that has all the
standard functions used for linux in gcc.

Any one know of where I should go?

Thanks
  Danny

Re: directories for newbies

[danny]

Hey Now That helps,

What I'm really looking for is documentation for these functions and many others.
Any place on line that any one knows of?

Thanks
  Danny

Re: directories for newbies

Hey Kayvan,

That helped too. Now I need a function that will let me determine the attributes of a
file. Specifically, I wanna know if a file is a directory or not. In the dos world
there was a program called dos_atrib. U got one like that for linux?

Also what I'd really like is some online manual that grouped all the standard lib
functions into different categories. Such as file management, networking, disk
management, strings, etc. Anything like that around?

One last thing on my wish list. A good debugger. Does linux have a standard debugger
already installed on my system? Any thoughts?

Thanks
  Danny

This is GNU debugger. man gdb for detail.

If you have vim editor installed, the following script will do
Unix (text file) to DOS conversion:
#!/bin/sh                           # Save u2d, chmod +x u2d
vim -c ":set ff=dos" -c ":wq" $1    # Usage: u2d filename.txt

Hey Now that helps thanks.

I'm look for a function to get me the attributes of a file. Such as is
the file a directory or not. Any ideas?

Thanks

All this is domain of the undelying OS (Linux) and has nothing to do with
gcc..

Try to read some book on Linux....
Linux is ** VERY ** diferent than DOS....

Try http://www.linuxdoc.org  first... There you'll have more references on
books, tutorials, and such thinks....

This list is for the compiler, not for general programming or Linux
specific ones...

There's a manual/info book on the C library:

info libc

(which can also be typeset):

and at <http://www.opengroup.org/onlinepubs/007904975/nfindex.html> is
the Base Definitions for POSIX, which is the standard that you should
actually be following when writing portable code :)

By no means everything is in there (e.g. you won't find JPEG readers or
graphical stuff in there), but the core stuff is.
