I have a program which accepts 2 N-digit numbers, multiplies them using threads & prints the output. The number of threads created here are 2 * N - 1. whenever I run the program for N > 151, the program gives me a segmentation fault. Is there a cap on maximum number of threads a process can get from the thread pool? If so, could thi...
I have a joinable pthread runner function defined as below: void *sumOfProducts(void *param) { ... pthread_exit(0); } This thread is supposed to join the main thread. Whenever I ran my program through Valgrind I would get the following leaks: LEAK SUMMARY: definitely lost: 0 bytes in 0 blocks indirectly lost: 0 bytes in 0 bloc...
While reading a book called "Let us C" I read that a function showbit() exists which can show you the bits of the number. There wasn't any special header file mentioned for it. Searched for it on the internet and didn't found anything useful. Is there such a function? I want this to print the binary of decimal numbers. Else please give m...
I'm trying to build up the proper data structure using a pseudo tcp header, tcp header, and tcp data to be sent to a check sum function to be verified. I cannot figure out what I'm doing wrong in my code. The following code is my function that builds up the data structure and then sends it to another function to be checked. void print_...
Hi. I'm writing a proxy library (called Library A) that is just an interface to another DLL (called Library B) that may be present or not on the system. The idea is that a program would link to this library A instead of the original library B ; and Library A would handle the errors if Library B wasn't installed on the system. So a typi...

Hi, In any programming environment,what ever the data type I am going to choose finally the CPU will do only the Arithmetic operations(addition/logical operations).

I have written a code where in it would take in a executable file and the [lib*.so] library as my arguments and link @ Run-time. I want to also take in the function in the (*.o) file @ run-time and link it. But I don't know how to go about it. EDIT 1: The function I'm trying to link is a part of the .o file in the lib*.so library. So I...
I am playing around with Cilk and I am having an issue with printing synchronously. Printing is slow, so it's hard to keep the prints synchronous. For example... void ftn(int x) { if (x % 2 == 0) { std::cout << "printing.. " << x << std::endl; } else { cilk_spawn ftn(x/2); cilk_spawn ftn(x++...
