close() system call does not return error?

Hi everyone,

I have experienced this when working in an embedded system linux RTOS, MontaVista Linux 4.0. I tried to hard code the function mapped to my close file operation by returning -1 at the end of the function, but in user space, calling close does not return an error, it returns 0. Is this a probable bug in the above linux distribution?

Best regards.

It doesn't seem so - the value should be returned correctly. However, can you check with a more typical error value like -EBADF?
