should be used instead.
|

POSIX 2024 defined this replacement interface because some broken legacy
|
||||
operating systems could fail with
|
||||
.Ev EINTR
|
||||
in
|
||||
.Xr close 2
|
||||
on slow devices,
|
||||
instead of returning 0 and either completing the operating in the background
|
||||
or aborting it.
|
||||
However, this means most programs need to be updated to use the more
|
||||
complicated alternative function instead for no practical gain, which isn't
|
||||
going to happen.
|
||||
The standard has added a lot of complexity where none needs to exist, which
|
||||
is rejected in this operating system.

.Xr close 2

never fails with

.Ev EINTR on this operating system.
