示例1: __fork_pty
# 需要导入模块: import pty [as 别名]
# 或者: from pty import STDERR_FILENO [as 别名]
def __fork_pty(self):
'''This implements a substitute for the forkpty system call. This
should be more portable than the pty.fork() function. Specifically,
this should work on Solaris.
Modified 10.06.05 by Geoff Marshall: Implemented __fork_pty() method to
resolve the issue with Python's pty.fork() not supporting Solaris,
particularly ssh. Based on patch to posixmodule.c authored by Noah
Spurrier::
