>Description:
Pipes are implemented as sockets and this is what fstat reports. However
send returns a "Socket operation on non-socket" error. Either socket
operations should work or fstat should report the file as a FIFO, not a socket.
This worked on 2.1.
>How-To-Repeat:
#include <unistd.h>
#include <stdio.h>
#include <sys/stat.h>
int
main ()
{
int fds [2];
struct stat statBuf;
char *data;
if (pipe (fds) < 0) {
perror ("pipe");
exit (1);
}
if (fstat (fds [1], &statBuf)) {
perror ("fstat");
exit (1);
}
printf ("pipe mode is: %o\n", statBuf.st_mode);
data = "some data to write";
if (send (fds [1], data, strlen (data), 0) < 0) {
perror ("but doing a send fails");
exit (1);
}
exit (0);
}
>Fix:
Unknown.
