About The Project

CthreAd is a multi-threading library which implements POSIX compliant threads in the Linux userland. Primarily, we have implemented two models of multi-threading:

• One-One

  One-One model of multi-threading maps each user-level thread with a kernel-level thread. All the threads can access the kernel at the same time. Even if a thread makes a blocking system call (i/o, etc.), other threads can continue to run.

  
  
  

• Many-One

  The many to one model maps many of the user threads to a single kernel thread. This model is quite efficient as the user space manages the thread management. The library performs the context-switch and scheduling operations.

  

Usage

To use CthreAd in your projects:

• Clone the repository using

  $ git clone https://gitlab.com/andipro123/cthread.git

• Move to the directory and choose the model you want to implement

  # for one-one
  $ cd cthread/one-one
  
  # for many-one
  $ cd cthread/many-one

• Compile the library

  $ gcc cthread.c -c -Wall
  
  #for many-one, use "cthread2.c"

• Include the header file in your project

  // Your C program
  
  #include<cthread.h>
  .
  .
  .

• Compile your project using

  $ gcc <your-project.c> cthread.o - o <your-project>
  
  #for many-one, use "cthread2.o"

Testing

The library comes with an automatic testing package to test all the functionalities of the threading library. Tests cover all areas of multi-threading to ensure that basic functions are working as expected. To run the tests:

$ make run
