Duplicate symbol when compiling

We will have duplicate symbol for architecture x86_64 when we compile the programs as follows:

$ g++ -c -Wall bye.cpp   # Generate bye.o
$ g++ -c -Wall hello.cpp # Generate hello.o
$ g++ -Wall main.cpp bye.o hello.o -o run

pthread

Sample code for demonstrating different behavior in different pthread type

• PTHREAD_MUTEX_NORMAL
  • This type of mutex does not detect deadlock
  • A thread attempting to relock this mutex without first unlocking it shall deadlock
  • A thread attempting to unlock a mutex locked by a different thread results in undefined behavior

Class in C for linked-list implementation

An example to simulate a C++ class in C.

This is a comparison to [ChunMinChang/8e04130e778d77e0b30b8954cc5f2473][c++], which implement a linked-list in C++.

TODO

• Implement delete function to remove a node from the list
• Implement move function to move cursor to a specific node
• Implement search function to return one specific node

Linked-list in C++

This is a comparison to [ChunMinChang/31f11789bb859356daf05107e8fc859e][class_in_c], which simulates C++ classes to implement linked-list in pure C.

TODO

• Implement delete function to remove a node from the list
• Implement move function to move cursor to a specific node
• Implement search function to return one specific node

Comparison with [C version][class_in_c]
