![]() ![]() Please note that the below program may compile only with C compilers with pthread library. Implementation of pthread is available with gcc compiler.Ī simple C program to demonstrate use of pthread basic functions POSIX Threads (or Pthreads) is a POSIX standard for threads. Unlike Java, multithreading is not supported by the language standard. Threads operate faster than processes due to following reasons:Ģ) Context switching between threads is much faster.Ĥ) Communication between threads is faster.Ĭan we write multithreading programs in C? MS word uses multiple threads, one thread to format the text, other thread to process inputs, etc. For example, in a browser, multiple tabs can be different threads. Threads are popular way to improve application through parallelism. But, like process, a thread has its own program counter (PC), a register set, and a stack space. ![]() Threads are not independent of one other like processes as a result threads shares with other threads their code section, data section and OS resources like open files and signals. What are the differences between process and thread? Because threads have some of the properties of processes, they are sometimes called lightweight processes. A thread is a single sequence stream within in a process. ![]()
