Named PIPE (FIFO) reading content of file in C - c

Question

Basically I want my client program to read data from a file (file name/path specified in the command line input) and copy that data to the FIFO and I want my server program to read from the FIFO and print every line.
For example if I want to print the contents of the /etc/passwd text file I run the program in the terminal in this way:
./server &
./client < /etc/passwd
However, instead of printing any output, it prints out nothing but 'done'.
Why?
Here's my code:
server.c
//server.c
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#define FIFONAME "myfifo"
int main(void){
int n,fd;
char buffer[1024];
unlink(FIFONAME);
//create FIFO
if(mkfifo(FIFONAME,0666)<0){
perror("server: mkfifo");
exit(1);
}
//open FIFO for reading
if((fd = open(FIFONAME, O_RDONLY))<0){
perror("server: open");
exit(1);
}
//READ from fifo UNTIL end of tile and print
//what we get on the standard input
while((n=read(fd,buffer,sizeof(buffer)))>0){
write(1, buffer, n);
}
close(fd);
exit(0);
}
.
client.c
//client.c
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
#define FIFONAME "myfifo"
int main(void){
int n,fd;
char buffer[1024];
/* open, read, and display the message from the FIFO */
if((fd = open(FIFONAME, O_WRONLY))<0){
perror("client: open");
exit(1);
}
//read from standard input and copy data to the FIFO
while (fgets(buffer, sizeof(buffer), stdin) != 0){
fgets(buffer, sizeof(buffer), stdin);
write(fd, buffer, n);
}
close(fd);
exit(0);
}

Answer 1

this code is wrong:
while (fgets(buffer, sizeof(buffer), stdin) != 0){
fgets(buffer, sizeof(buffer), stdin);
write(fd, buffer, n);
this loops consumes the input, then reads it again. You're losing the first (and possibly the only) buffer. I would do (maybe not the best code but works):
while (1){
if (fgets(buffer, sizeof(buffer), stdin)==0) break;
write(fd, buffer, n);
}
Aside, as noted in my comments, running the server in background to create the FIFO and running the client without waiting for the FIFO to be created is a potential race condition.
