QPing

Read this in other languages: English, 한국어

• Ping class for Qt 5 or 6

• You can check the response by shooting the ping.

Note

• I do not call functions that use the ICMP protocol.
  • I have written a raw socket program for pinging in the past.
  • But there’s a problem with user’s elevation. Application should be executed by root or superuser.

How to use

• Copy QPing.h, QPing.cpp to your project.

• Append Qt project(*.pro) setting of source code

HEADERS += QPing.h
SOURCES += QPing.cpp

• Add source code that applies the class. See main.cpp.
