fledgling
hello everyone In no less than 5 months I will be graduating and moving on to college. I plan to study computer engineering. I know that I *will* be able to skip some courses, especially if it has to deal with programming. I would like to know how database programming stands though. Can someone tell me a real world database program that would be needed? I want to test what I know. Thanks, in advance, for any suggestions, help, etc. _ Do You Yahoo!?

I have a really messed up problem I'm trying to compile and install libcap then libnet.

Can someone pelase tell me where I can get these header files? I'm using libc5 rh 4.2 btw. thanks, in advance, for anyhelp _ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
foolish compile problem
i'm doing a: gcc -lX11 file.c and i get the err: ld: cannot open -lX11: No such file or directory But I'm sure I have the Xlib because I've installed its rpm I've cated /usr/lib/X11R6 /etc/ld.so.conf and also all the other dirs that has libs on my system. And I've also ran ldconfig. How can I fix this? Thanks, in advance, for any help. _ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
Re: your mail
I don't use emacs much but I use vim. One way you can do what you're trying to do is by first making a Makefile (learn how to make them :-]) then, has to be in the same directory editing your source file with vim then you'd just have to hit escape then colon (:) and type make, after that you can type ":make run" (if you've made your Makefile well). --- Wei Weng [EMAIL PROTECTED] wrote: You can always use shell command from emacs. (is it M-x ! command_name?) Say have two window open in one frame under emacs. One is for editing and another one is for the gcc thingy. I don't know if there is any emacs scripts for making your programming more convenience(sp?). I like the way it is. I just open more windows. :) On Wed, 31 Mar 1999, Darius Blaszijk wrote: Hi all, Having my latest problems using DOS/WINDOWS, I decided to start programming under LINUX. I installed LINUX redhat 5.2 and bought myself the book L.A.D. I must say that I'm getting on quite well (I had to learn also how to program in C). But here is where my problems start. To do some programming I use for instance EMACS. When I'm done I exit EMACS and run GCC and then run the program to see if it does the thing I want it to do. This procedure is time consuming and not eficient. Is there any compiler/editor/debugger-package anvailable from the internet? Or am I missing something here? I've noticed that MC has an edit feature which shows source code using different colours. I find this very helpfull.

Re: filecopy
first man open
#include errno.h
if ((in = open(source, O_RDONLY)) == -1)
{
perror("open"); /* should print reason */
exit(1);

such). What is the best way to do this ?

How can I find out if a process is already using a mtype (sys/msg.h) so that no conflicts arise? _ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com
Simple questions.
On Sys V, how do I make my program respond to a key bind like ^R? I want the program to run in the background and for it to take commands such as the one from above while still in the background. Thank you. _ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com
A problem with ncurses
I've initalized an array of windows by using... WINDOW *win[6]; For some reason win[0], dosn't want to move. It's color attribute, like the others, was correctly set, but it's the only one which does not change position. In fact... after having... for(i = 0; i 6; i++) /* win[6], is being used for something else. */ win[i] = newwin(1, 1, i + 1, i + 1); Then I have the attributes set then after I move every other windows (which happens alot and perfectly too) win[0] fails to respond. I have no idea how this could happen, can anyone help? _ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com

Why does there exists a VPFN if a process is going to use only one PFN. (VPFN = Virtual Page Frame Number) (PFN = Page Frame Number) The thing is I'm understanding the concept well. When a process is mapped to its Virtual Page where does the instructions go? What does the offset part (on an x86 it's 11:0 and below) do? And why does it need a VFPN? The reason why I need to know these things is because I'm soon going to get into IPC programming and I believe that I most know these for it to be easier. _ DO YOU YAHOO!?
