read / write on socket descriptors linux c - sockets

Question

I am trying to send the contents of a file from the server to the client , I am reading the file line by line using fgets and writing to the socket descriptor line by line , on the client side , i am in an a while loop , reading the sent contents.I am not being able to terminate the server sending sequence , i.e the client keeps reading the buffer and the next program line is not executed , I think thers something wrong with my way of sending or recieving . here is the code :
server :
filefd = fopen("clients.txt","a+");
while(fgets(filcont,300,filefd) != NULL)
{// write whole file contents to client
n=write(newsockfd,filcont,strlen(filcont));
if(n==0) break;
memset(filcont,'\0',300);
}
fclose(filefd);
client side :
while(n>0){
n = read(sockfd,buffer,sizeof(buffer)-1);
if(n==0) break;
printf("%s\nbytes read :%d \n",buffer,n);
memset(buffer,'\0',256);
}
printf("Enter peer name ( except yours ) to send connection request : \n");
the above line ( printf , peer name doesnot get executed until i terminate the server)

Answer 1

I was able to figure it out , I sent the file contents from the server using fread instead of fgets ( line by line ) and used a single read() at the client . this was the quick fix.
But I also figured out another technique when in case you have to compulsorily use fgets , where the while loop at the client side makes the socket nonblocking for read and then blocking again , the code is pasted below.
flags = fcntl(sockfd, F_GETFL, 0);
fcntl(sockfd, F_SETFL, flags | O_NONBLOCK);
while(n>0){
n = read(sockfd,buffer,sizeof(buffer)-1);
if(n==0) break;
if(n==-1) printf("\nNon blocking read failed congrats");
printf("%s\n",buffer);
memset(buffer,'\0',256);
}
printf("\nbytes read :%d \n",n);
val = fcntl(sockfd, F_GETFL, 0);
flags = O_NONBLOCK;
val &= ~flags; // makes it blocking again
fcntl(sockfd,F_SETFL,val);
The code from stackoverflow was refered to make the socket blocking
