Moreover, the wording also disallowed using 0 (i.e., no flags at all), which POSIX specifically allows; I tested the function with no flags and it worked fine for me, so I guess it was a problem with the documentation, and not with the implementation itself. POSIX ref: https://pubs.opengroup.org/onlinepubs/9699919799/ Signed-off-by: Alejandro Colomar --- Hi Michael, I was working with the example, and the documentation was a bit weird, so I want to be sure I'm doing it right before sending you the example. Please review that this patch is correct, which I guess it is.
