    Description

      I'm afraid I only have a PyQt example ready for this:

      With this code:

      from PyQt5.QtCore import QCoreApplication
from PyQt5.QtNetwork import QLocalServer

app = QCoreApplication([])

QLocalServer.removeServer('/tmp/ipc-test')

s1 = QLocalServer()
ok = s1.listen('/tmp/ipc-test')
print('s1: {}'.format(ok))
print(s1.errorString())

s2 = QLocalServer()
s2.setSocketOptions(QLocalServer.UserAccessOption)
ok = s2.listen('/tmp/ipc-test')
print('s2: {}'.format(ok))
print(s2.errorString())
print(s2.serverError())

      I don't get an AdressInUseError like I'd expect:

      s1: True
s2: True
-1

      When commenting the setSocketOptions line, it works as expected:

      s1: True
s2: False
QLocalServer::listen: Address in use
