mknod issue

Hi Friends,

I'm getting a mknod error while executing this program which
is to create a named fifo.
What is wrong with this usage? It will be really helpful
to correct me.

#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>
#include <sys/stat.h>
#include <sys/types.h>

#define FILE_NAME "/home/dejose/linux/named-fifo"

int
main()
{
int wr_desc, err_no;

err_no = mknod(FILE_NAME, S_IFIFO | 0666, 0);
if (err_no < 0) {
printf("\nmknod error = %d", err_no);
return;
}

wr_desc = open(FILE_NAME, O_WRONLY);
if (wr_desc < 0) {
printf("\nopen error");
}

write(wr_desc, "My first named fifo", strlen("My first named
fifo"));
}

Thanks,
Deepak

No idea. What error do you get?

The 'mknod' call does not return an error number.

"mknod() returns zero on success, or -1 if an error occurred
(in which
case, errno is set appropriately)."
