Uresolved inclusion of header files

[zaman ahmad]

I included header file but it is not resolved. following header files are causing problems termios.h, sys/socket.h, sys/ioctl.h, netinet/in.h, netinet/ip.h, netinet/tcp.h, arpa/inet.h

    #include <stdio.h>
    #include <string.h>
    #include <stdlib.h>
    #include <stdint.h>
    #include <termios.h>
    #include <sys/time.h>
    #include <unistd.h>
    #include <errno.h>
    #include <limits.h>
    #include <fcntl.h>
   
    /* TCP */
    #include <sys/types.h>
    #include <sys/socket.h>
    #include <sys/ioctl.h>
    #include <netinet/in.h>
    #include <netinet/ip.h>
    #include <netinet/tcp.h>
    #include <arpa/inet.h>
   
    #include "modbus.h"
