Debian Programming :: What Is Purpose Of Parameter Within Single Quotation Marks
Oct 20, 2014
what is the purpose of the parameter within single quotation marks and what it does? I am assuming it is a call to pkg-config with those paramaters.
Code: Select allgcc -o gtkprog gtkprog.c `pkg-config --libs --cflags gtk+-2.0`
Using:
Code: Select allpkg-config --libs --cflags gtk+-2.0
-pthread -I/usr/include/gtk-2.0 -I/usr/lib/x86_64-linux-gnu/gtk-2.0/include -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/libpng12 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng12 -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/freetype2 -lgtk-x11-2.0 -lgdk-x11-2.0 -lpangocairo-1.0 -latk-1.0 -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lpangoft2-1.0 -lpango-1.0 -lgobject-2.0 -lglib-2.0 -lfontconfig -lfreetype
So, if my logic serves me right, this command parameter is a neat replacement for this litany of libraries to be used in the compilation process.

I'm writing some code to speed up some code writing, basically it produces some code I use in every project. I produce the outputs with fstream filestr;, open a file and write to some data to it. However some code has quote marks that I need to output, however I can't use quote marks.
EG: filestr<<"#include "Header.h""<<endl;I get round this with some awful filestr.put ('"');However I'm sure there must be a straight forward way to do this. Can anyone advise?

I want to put a string, such as the one found in the image, into an array that will later be chopped into individual words and put into another array of individual words found in the initial string. (or, perhaps, I would be able to do that initially, but for now, that is the goal)My question is, how can I do that without using quotation marks?

I tried to move a file from my desktop to another folder; moving it was not allowed, for some reason. Neither was opening it and saving a new copy in the target folder. Would that be because the filename contains double (") quotation marks? Are they not allowed? The filename is Edit of Bob's "Lady Liberty" Article.doc. [Filename not enclosed in quotation marks here, to avoid confusion.]I just changed the double quotation marks to single quotation marks; that solved everything.

I'm wondering if anyone can give me some guidance, or point me to a relevant reference for setting up a single purpose ssh key.I have setup a single purpose key for rsync, where I have command="/path/to/rsync-secure" associated with the public key in .ssh/authorized_keys, and the rsync-script checks to make sure incoming commands begin with 'rsync --secure', What I would like to do is do something similar to allow sshfs access, and have the server path that can be mounted locked down to a particular location. Does anyone have any suggestions as to how this could be done?As an aside, I might also want to restrict the above rsync script to only allow synchronization to a particular path.

I learned Java(SE,EE) few years ago and didn't use it because we are using PHP and ASP.NET at work.However, I would like to ask a question: Is Java (SE,EE) free for use for business purpose?I mean,if I start up a company and use tomcat with java, do I have to pay for the license to use Java?I don't know much about java license until I learned that ASF(Apache Software Foundation) quited from the Java Community recently.As a result,they recalled my attention regarding the legitimacy of using java in business purpose for free.

I have a small board that has a static ram board attached to it. I have two different programs that each write to a byte of memory in the static ram board. I get a file descriptor to the device memory with the following code:
int phymemfd;
phymemfd=open("dev/mem, O_RDWR | O_SYNC);
This opens the physical memory for both reading and writing. Next I get a pointer to the beginning of my ram board.
volatile unsigned char *novram;
novram = (unsigned char *) mmap(0, getpagesize() * 31,
PROT_READ|PROT_WRITE, MAP_SHARED, phymemfd, 0x11AA0000);
I do this same code in two processes that are both running and this works fine. Now, if I take out the O_SYNC parameter, one of the programs gets into some sort of weird state.My understanding of the O_SYNC parameter is that it cause the process accessing the memory location to block, not allow another process to run, until the first process has finished writing to it.I can see that if my program doesn't block, I wouldn't really know what was in the memory location, but would I can't see how it would cause any other type of system problem.

Say, i have an imaginary std library function, which I want to call.
Code:
void std_lib_func(ObjectType *param);
Now in my c++ program, I have a main() function, and I will like to call a customized function (which will in turn call the std lib function) from the main function, as below:
Code:
int main()
{
ObjectType *aobj;
customized_func(aobj);
}
[Code]...
I tried the below but get an error that the std lib function is expecting a ObjectType* param, not aobj. How should I work this out.
Code:
void customized_func(ObjectType aobj)

A simple TCP based chat server could allow users to use any TCP client (telnet, for example) to communicate with each other. For this question you should consider a single process, single thread server that can support exactly 2 clients at once, the server simply forwards whatever is sent from one client to the other (in both directions). Your server must not insist on any specific ordering of messages as soon as something is sent from one client it is immediately forwarded to the other client. As soon as either client terminates the connection the server can exit

i googled around and finally stumbled over this forum. I've been wondering, how would i kill an process running from an folder and with user parameter? I usually type this into the ssh console: pkill -9 < process > -U < username >
But i want users be able to run it multiple times, and killing only an specific process and not every single one.

i want a process that can operate as both a TCP echo server and a UDP echo server. The process can provide service to many clients at the same time, but involves a single process that does not start up any other threads.

In the rpm manual, Print 50 hash marks as the package archive is unpacked. Use with -v|--verbose for a nicer display. But actually, there're not enough hash marks when I'm installing a package. About 44 hash marks there...Well, I just want to know where the `50 hash marks' are.
