Python : SIGABRT: Abort signal
SIGABRT : Abort Signal
OS module in Python provides functions for interacting with the operating system. OS comes under Python%u2019s 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() .
This method does not return any value in the calling
process.
Example:
Use of os.abort() method
# Python program to explain os.abort() method
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:
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 ! World")
# Abort the child process
# by generating SIGABRT signal
# using os.abort() method
os.abort()
Output :
In child process
Process ID: 13914
Hello! World
In Parent process
Child stopped due to signal no: 6
Signal name: SIGABRT
