Sol92:

This code is used inside the func() function to read and write data to the socket descriptor sockfd.

The write() function is used to write data from the buff buffer to the socket descriptor. It takes three arguments: the socket descriptor (sockfd), the buffer containing the data to write (buff), and the size of the buffer (sizeof(buff)).

The bzero() function is used to clear the buff buffer before reading data from the socket descriptor. It takes two arguments: a pointer to the buffer (buff) and the size of the buffer (sizeof(buff)).

The read() function is used to read data from the socket descriptor into the buff buffer. It takes three arguments: the socket descriptor (sockfd), a pointer to the buffer that will hold the data (buff), and the size of the buffer (sizeof(buff)).

The printf() function is used to print the data that was read from the socket descriptor to the console.

The strncmp() function is used to compare the first 4 characters of the buff buffer with the string "exit". If the two strings are equal, the program prints a message indicating that the client is exiting and breaks out of the loop that is handling the communication between the client and server.
