• C-language Header files for Network Programming
  • Network programs written in C must include the following header files to define the necessary data structures used by the Socket API:

    #include <stdio.h> // Standard IO, all C programs need this #include <stdlib.h> // Standard Library, all C programs need this #include <sys/types.h> // System variable types #include <sys/socket.h> // Type definitions related to sockets #include <netinet/in.h> // Type definitions related to Internet protocol #include <arpa/inet.h> // Network utility functions #include <netdb.h> // Name services functions
