Practical C Programming

How to do it…

1. Open the FIFO special file in read-only mode by invoking the open function.
2. Read the text from the FIFO special file using the read function.
3. Close the FIFO special file.

The readfifo.c program for reading from the named pipe (FIFO) is as follows:

#include <fcntl.h>#include <stdio.h>#include <sys/stat.h>#include <unistd.h>#define BUFFSIZE 255int main(){    int fr;    char str[BUFFSIZE];    fr = open("FIFOPipe", O_RDONLY);    read(fr, str, BUFFSIZE);    printf("Read from the FIFO Pipe: %s\n", str);    close(fr);    return 0;}

Let's go behind the scenes.
