C++ TCP IP SERVER CLIENT Komut gönderme

[serkank]

C++ ile Multi Client Server bir program yapmak istiyorum Echo Orneği var ama bunu Komut gönderme almaya ceviremedim. Pc nizde varsa Bana boyle bir program örneği gönderebilirmisiniz yada bir link ?

Hangi kitaplıkları kullanıyorsun, .NET mi mfc mi yoksa klasik konsol uygulaması mı yapmaya çalışıyorsun. Hanig ide yi kullanıyorsun. Server tarafını mı client tarafını mı yapmak istiyorsun? Aşağıdaki linkte standart kitaplıklarla konsol uygulaması yapılmış işine yarayabilir. Yada üzerinde uğraştığın örneği paylaş inceleyelim.

Orange Pi Zero + VisualStudio code + SSH Plugin 'i ni kullanıyorum Klasik Konsol uygulaması olucak. amacım OrangePi Zero ile Otomasyon Uygulaması yapmak .. TCP ip Uzerinden Kontak1_ON - Kontak1_OFF Şeklinde datalar gönderip Orangepi ye bağlı Röle leri açıp kapatmak.
Role Kontakları ve Bununla ilgili Kodu yaptım fakat TCP Server'ı yapamadım
Aşağındaki Echo Server Kodu ile uğraştım ama Clientten gönderdiğim Kodu Serverdan Nasıl Kontrol etmesini yapamadım . Kodun En altına Bu kodu ekledim.. Clienttan Kontak1_ON gönderiyorum ama server bunu almıyor..
// if (strcmp(buffer , 'Kontak1_ON') == 0 ){ // printf("Kodu aldı"); // }
