Are still some c++ jobs around by 2025? It looks like classic c++ jobs already dead or dying.

Hi anyone can share EC/TDS sensor library for proteus?

It is not dead and it is not dying

Most of the programs you use nowadays are either written in or powered by C++ or C Such as browsers, search engines, compilers and runtimes, games

Hi all. How to get the pid of a locally connected unix socket from a local application?

Simple Sorcerer sent a code, it has been re-uploaded as a file

This is roughly what I am doing. the socket of course works fine and accepts local unix socket connections

I have an error with the "ancillary data" setting everything else works fine. i can't understand the documentation again

To receive credentials such as the PID, UID, and GID from a UNIX domain socket, you need to set up your socket and message structures properly. The credentials are passed as ancillary data in the control message of the recvmsg() system call. Here are some common issues and solutions to consider: Common Issues & Fixes: 1. Ensure `SO_PASSCRED` is Set on the Socket: You've correctly enabled SO_PASSCRED on the socket, which is necessary to receive the credentials. 2. Setting up `struct msghdr`: The struct msghdr needs to be correctly set up to receive ancillary data. It looks like you are not setting up all required fields (`msg_name`, msg_namelen, msg_iov, msg_iovlen, msg_control, msg_controllen, `msg_flags`). 3. Setting up Ancillary Data Buffer Correctly: The buffer for ancillary data (`cmsg`) must be sufficiently large to hold the control message header plus the actual data (`struct ucred`). You're currently only allocating space for struct cmsghdr, which isn't enough. 4. Check for Proper Use of `recvmsg()`: The way you're checking the return value of recvmsg() is incorrect. You should check if it returns -1 for an error. Also, SCM_CREDENTIALS is not a flag for recvmsg(), it's used with the control message. Here's how you can correct these issues: // Set up the buffer for receiving the credentials struct ucred cred; char buf[BUFSIZ]; // adjust size as needed struct iovec iov = { .iov_base = buf, .iov_len = sizeof(buf) }; struct msghdr msg = {0}; char control[CMSG_SPACE(sizeof(cred))] = {0}; // reserve space for ancillary data msg.msg_iov = &iov; msg.msg_iovlen = 1; msg.msg_control = control; msg.msg_controllen = sizeof(control); ssize_t nbytes = recvmsg(new_sock, &msg, 0); if (nbytes < 0) { perror("recvmsg"); } else { for (struct cmsghdr *cmsg = CMSG_FIRSTHDR(&msg); cmsg != NULL; cmsg = CMSG_NXTHDR(&msg, cmsg)) { if (cmsg->cmsg_level == SOL_SOCKET && cmsg->cmsg_type == SCM_CREDENTIALS) { memcpy(&cred, CMSG_DATA(cmsg), sizeof(cred)); printf("PID: %d, UID: %d, GID: %d\n", cred.pid, cred.uid, cred.gid); break; } } } // ... close(new_sock); Additional Notes: - Ensure you include the necessary headers (`<sys/types.h>`, <sys/socket.h>, <sys/uio.h>, etc.). - The control message is aligned to the nearest size required by the system, so it's essential to use macros like CMSG_SPACE for allocating the control buffer. - The buffer buf in the iov structure is used to receive the primary data over the socket. If your protocol involves sending/receiving primary data before/along with the credentials, make sure to handle this data appropriately. - Error checking is crucial. Make sure to check the return values of each call and handle errors as needed.

I can't get anything to work. now I've completely broken my code :D

Guys why so many people quit programming while it is one of the most exciting activity and most paid skill in way of mastering.

How on earth can someone understand cppreference I spend a lot of time rereading paragraphs and words and it feels so stupid and frustrating

Some bits of the language absolutely are complicated and use specific vocabulary, but I want to say that you'd better get accustomed to not knowing things because upon starting to work in a company, you will be pretty confused by their ecosystem

Guys what do u think which is better combination for success: math + programming or physics + programming? Learning three of these things for getting the best result is unrealistic imo.

Or just trying to focus more on one thing (programming)?

I believe master physics is irrelevant for software than math. Let's keeping hardware industry on China. 😂

If you want to study physics, then in any case you need good knowledge of mathematics. Including higher mathematics :D

Hi

Does someone has a link or good explanation of forwarding references and references collapsing These topics seems really confusing, I even recalled that type of confusion when a beginners tries to grasp pointers

Read Meyer's book called "Effective Modern C++". I think he wrote a good explanation.

I remember reading that book when I was a novice to intermediate level It was a frustrating and terrible experiment

Could you give me a starting idea or basic logic on how I can find rref

Reference in what context? Share your code, your question is incomplete. Do you want to modify the 2d array in place? Where are you accessing this 2d array? Are you passing it in a function?

int array[5]; array[5] = 88; sizeof(array) > 20bytes printf("%d",array[5]) -> 88; Allocated memory 20 bytes but after add array[5] = stored in array and also accessible

int array[5]; array[5] = 88; sizeof(array) > 20bytes printf("%d",array[5]) -> 88; Allocated memory 20 bytes but after add array[5] = stored in array and also accessible

run valgrind on it, you will see that array[5] is invalid assignment

int array[5]; array[5] = 88; sizeof(array) > 20bytes printf("%d",array[5]) -> 88; Allocated memory 20 bytes but after add array[5] = stored in array and also accessible

To avoid such questions, you should familiarize yourself with the character code. A Wikipedia page is enough for this.
