Python | os.abort() method

Last Updated : 26 Aug, 2019

OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality.

os.abort() method in Python is used to generate a SIGABRT signal to the current process. On Unix, this method produces a core dump while on Windows, the process immediately returns an exit code of 3.
This method does not call the Python signal handler registered for SIGABRT signal with signal.signal().

Syntax: os.abort()

Parameter: No parameter is required.

Return type: This method does not return any value in the calling process.

Code #1: Use of os.abort() method

# Python program to explain os.abort() method  
  
# importing os module   
import os 
  
  
print("Hello ! Geeks") 
  
# os.abort() method 
# will generate 'SIGABRT' 
# signal to the current process 
# On Unix, a core dump 
# will be produced 
# On windows, process 
# will exit with exit code 3 
os.abort() 
  
# As process is aborted 
# the line after os.abort() statement 
# will not be executed. 
print("This will not be printed") 

Output:

Hello! Geeks
Aborted (core dumped)

Code #2: Use of os.abort() method

# Python program to explain os.abort() method  
  
# importing os module   
import os, signal 
  
# Create a child process 
# using os.fork() method  
pid = os.fork() 
  
  
# pid greater than 0 
# indicates the parent process  
if pid > 0: 
    # Parent process     
    print("\nIn Parent process") 
      
    # Wait for the completion  
    # of child process and get  
    # its pid and exit status indication 
    # using os.wait() method  
    info = os.wait() 
          
    sig = os.WTERMSIG(info[1])  
    print("Child exited due to signal no:", sig) 
    print("Signal name:", signal.Signals(sig).name) 
  
else : 
  
    # child process 
    print("In child process") 
    print("Process ID:", os.getpid()) 
    print("Hello ! Geeks") 
      
    # Abort the child process 
    # by generating SIGABRT signal 
    # using os.abort() method 
    os.abort() 

Output:

In child process
Process ID: 13914
Hello! Geeks

In Parent process
Child stopped due to signal no: 6
Signal name: SIGABRT
