1. Hello,
Ther is some problem in you code
I made my own programme as per your requirement
Please check my solution :-
1)Create one FIFO
2)From Client write character first and wait for some time so that server will read it
3) After wait for some time write integer
Server programme :-
---------------------------------------
#include
#include
#include
#include
#include
int main()
{
int client_to_server;
char *myfifo = "/tmp/client_to_server_fifo";
char str;
int iteration;
/* create the FIFO (named pipe) */
mkfifo(myfifo, 0666);
/* open, read, and display the message from the FIFO */
client_to_server = open(myfifo, O_RDONLY);
printf("Server ON. ");
read(client_to_server, &str, sizeof(str));
read(client_to_server, &iteration, sizeof(iteration));
close(client_to_server);
unlink(myfifo);
//Now Print the character
for(int i = 0; i < iteration ; i++){
printf("Iteration ::%d and Character:: %c ",i,str);
}

2. return 0;
}
Client Programme :-
---------------------------------------
#include
#include
#include
#include
#include
int main()
{
int client_to_server;
char *myfifo = "/tmp/client_to_server_fifo";
char str;
int iteration;
printf("Client: Please enter a character: ");
scanf("%c", &str);
printf("Client: Please enter an integer: ");
scanf("%d", &iteration);
/* write str to the FIFO */
client_to_server = open(myfifo, O_WRONLY);
//First write character
write(client_to_server, &str, sizeof(str));
//wait for some time so that server will read character
sleep(0.250);
//Then write integer
write(client_to_server, &iteration, sizeof(iteration));
perror("Write:"); //Very crude error check
printf("...received from the server: %s ",str);
close(client_to_server);
/* remove the FIFO */
return 0;
}
