Python中的OS模块提供了与操作系统进行交互的功能。操作系统属于Python的标准实用程序模块。该模块提供了使用依赖于操作系统的功能的便携式方法。

os.abort()Python中的方法用于生成到当前进程的SIGABRT信号。在Unix上，此方法产生一个核心转储，而在Windows上，该过程立即返回退出代码3。此方法不使用signal.signal()调用为SIGABRT信号注册的Python信号处理程序。

用法： os.abort()

参数：不需要任何参数。

返回类型：此方法在调用过程中不返回任何值。

代码1：用于os.abort()方法

# 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")

输出：

Hello! Geeks

Aborted (core dumped)

代码2：用于os.abort()方法

# 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()

输出：

In child process

Process ID: 13914

Hello! Geeks

In Parent process

Child stopped due to signal no: 6

Signal name: SIGABRT
