function::thread_indent - Linux

Overview

The function::thread_indent command is used to determine the indentation level of a given thread. It is primarily used for debugging purposes in multithreaded applications to identify the level of nesting within a specific thread.

Syntax

function::thread_indent ( thread )

Options/Flags

None.

Examples

Consider the following snippet:

import threading

def nested_function(thread):
    function::thread_indent(thread)
    print("Nested function called from thread", thread)

def main():
    t1 = threading.Thread(target=nested_function, args=(1,))
    t2 = threading.Thread(target=nested_function, args=(2,))

    t1.start()
    function::thread_indent(t1)
    print("Main thread calling nested function")
    t2.start()
    function::thread_indent(t2)
    print("Main thread joining threads")
    t1.join()
    t2.join()

if __name__ == "__main__":
    main()

This script will produce the following output:

Nested function called from thread 1
  Main thread calling nested function
    Nested function called from thread 2
      Main thread joining threads

Common Issues

Using function::thread_indent outside of the context of a threaded application will return an error.
Incorrectly passing non-thread objects as arguments will lead to type errors.

Integration

function::thread_indent can be used alongside other debugging tools to provide a comprehensive view of thread execution. It can be used in combination with thread synchronization mechanisms like locks and semaphores to analyze thread behavior.
