[MrAta]

Hi,
In writing example I get Got error: 9.
what means that?
thank.

Hello! I think 9 == EBADF which means bad file descriptor

This error can occur both reading or writing.

EBADF fd is not a valid file descriptor or is not open for {reading [1], writing [2]}

[2] - http://man7.org/linux/man-pages/man2/write.2.html

Maybe you are writing in a file in which write is not allowed? or something similar. If this don't help, could you provide your code snippet?

thanks

I met this problem too, and I solve like this:

in my situation, i write new file each time, when call os.open with os.O_WRONLY, it occurs "File Not Exists", and with os.O_CREAT it callback with errno 9.
finally, i call os.open with os.O_CREAT|os.O_WRONLY, it runs well.

fd = os.open(absolute_path, os.O_CREAT|os.O_WRONLY)
