Again a driver question ..If someone knows ..Plz let me know..I have a driver -usb hub driver ..I need to do something based on kernel command line options which is provided by the bootloader..I know by module param I can read parameters provided to modules but I want to read from kernel cmdline..In user space I can do it by Cating /proc/cmdline or directly use "open" functions in C but I need to get it done in usb hub driver....I even have that parameters as char* in main.c of kernel but again there is headache of passing that to driver...How can I directly read it in usb driver?Already cheked major blogs ditnt quite got the solution..

Does this help? https://github.com/torvalds/linux/blob/v4.12/Documentation/admin-guide/kernel-parameters.rst

Yes even tried with setup call..But that seems to be depreciated...So was looking for more clean and trusted and time saving way .

That is something they expect people to know before they even register for their courses. Basically you should be comfortable with Python, bash and Linux OS (daily use) in general. For CTP and OSEE, they also need you to know additional things like C/C++, assembly amongst others.

Hi guys, I know C very well and I got a question: Is easy making desktop app (with gui) in C++? I already have a good starting point knowing C should I learn C++? I always built desktop app in Javafx with Scene Builder bit it sucks a lot. C++ allows me to make the same but without freaking out every time?

Use SDL and draw pixels

So should I keep in Java?

Oh I see now I googled it

That's a little bit far from what i'm looking for. What I want is a Scene Builder alternative in C++ that urge me to learn C++, because Scene Builder works like shit

Yea yea that's fair but I don't want to write all the code that I need to make a good looking gui, the backend is already enough yk?

If you draw pixels it's already portable, you don't need to port SDL because that the basic thing

It's not what I am looking for, I need the OOP for what I want to make

I don't know much about the details but Qt framework is good for making GUIs. There are also other libraries but I think Qt is the easiest, but they are all better than making GUIs using Win32 library or smth like that of course

Yep I already know about the lib but it's still a lib I don't want to code for my gui app I just want to drag and drop as Scene Builder

You guys are talking about desktop C/c++ applications..any C++ for networking programmer?

they talking about qt framework

I'm not used to Qt framework

Scene Builder is just for javafx and I love java and javafx but the scene builder software sucks and I don't want to use it anymore, I don't have fun with it

Java doesn't produce native applications which hurts my OCD

Do you ever used scene builder? Let me know how your OCD increase after one hour of Scene Builder😂

Scene builder delete some part of your gui after the savings

Is it a bug or an AI to improve the app

The only one with a simple drag and drop

You can't use that for bigger projects thats my guess

@admin y u dont start code competition

You dont waste your time coding the position of the elements or the colors or whatever is just a "squeezingBallStuff", yea i like to speak french sometimes ahahhaha

Qt Designer can be an alternative: drag and drop without wasting your time coding for layout or color...

Really? And it works with c++ java or what?

Can gtk library be included in vs code? If yes, then how? Im very new to this and trying to create gui in c. If you all could help me out in this or if you have further suggestions as to which toolkit is easier to use please do share

use linux, and write a many cli apps before use the gui

because at linux the library linking is very simple, most of cpp packages can be install via "apt install"

vs code needs a write the configurations, plase use another ide for cpp gui

So it cant be done on vs code?😔

In windows we use fflush(stdin) for removing buffer What we do in linus for removing budget value Anyone please

Flushing stdin is a bad practice. It results in Undefined behavior and must be avoided. Fflush should be used on input streams only when you are working on an underlying seekable file and stdin is not.

#include<stdio.h> #include<string.h> #include<stdlib.h> struct mobile { char brand[27]; int quantity; int price; }; int count=0; void storing(struct mobile *ptr) { fflush(stdin); printf("\n\nEnter the details of %d mobile \n",count+1); printf("Brand name :"); gets(ptr[count]->brand) ; printf("Quantity :"); scanf("%d", &ptr[count]->quantity) ; printf("Price : "); scanf("%d", &ptr[count]->price) ; count++; } void search(struct mobile a[],int n) { fflush(stdin); int key; char find[27]; printf("enter the mobile brand\n"); gets(find); for(int i=0; i<n; i++) { key = strcmp( a[i].brand , find ) ; if( key == 0 ) { printf("Mobile brand : %s \n", a[i].brand) ; printf("Quantity : %d \n", a[i].quantity) ; printf("Price : %d \n", a[i].price); } } } int main() { struct mobile m[3]; while(1) { printf("enter your choice \n 1.storting \n 2.searching\n 3.exit\n"); int ch; scanf("%d",&ch); switch(ch) { case 1: storing(m); break; case 2: search(m,3); break; case 3: exit(0); } } } what is wrong with this ?

It looks okay

#include<stdio.h> #include<string.h> #include<stdlib.h> struct mobile { char brand[27]; int quantity; int price; }; int count=0; void storing(struct mobile *ptr) { fflush(stdin); printf("\n\nEnter the details of %d mobile \n",count+1); printf("Brand name :"); gets(ptr[count]->brand) ; printf("Quantity :"); scanf("%d", &ptr[count]->quantity) ; printf("Price : "); scanf("%d", &ptr[count]->price) ; count++; } void search(struct mobile a[],int n) { fflush(stdin); int key; char find[27]; printf("enter the mobile brand\n"); gets(find); for(int i=0; i<n; i++) { key = strcmp( a[i].brand , find ) ; if( key == 0 ) { printf("Mobile brand : %s \n", a[i].brand) ; printf("Quantity : %d \n", a[i].quantity) ; printf("Price : %d \n", a[i].price); } } } int main() { struct mobile m[3]; while(1) { printf("enter your choice \n 1.storting \n 2.searching\n 3.exit\n"); int ch; scanf("%d",&ch); switch(ch) { case 1: storing(m); break; case 2: search(m,3); break; case 3: exit(0); } } } what is wrong with this ?
