open function returns error

sudheernair · 05-07-2004, 09:22 AM

i am creating a pipe for communication. for that i created a file with mkfifo passing a file path. after that i try to open the file with open function passing same file path. but it returns -1 and perror says 'no such device or address'. when i check the path, there is file created and present. why it like that. the same code worked earlier...
Thanks

Make sure there's a process trying to read from the fifo before opening with "O_NONBLOCK" specified to the open function.

Or don't use "O_NONBLOCK"...
