.Xr close 2
|
||||
never fails with
|
||||
.Ev EINTR on this operating system.
|
||||
.Ss posix_devctl
|
||||
.Xr ioctl 2
|
||||
should be used instead.
|
||||
POSIX 2024 defined this optional function as a replacement for
|
||||
.Xr ioctl 2
|
||||
but never defined any way for portable applications to actually use it.
|
||||
The
|
||||
.Fa dev_info_ptr
|
||||
parameter is especially useless as its semantics are not defined, and often
|
||||
the desired output does not necessarily fit in an int type.
|
||||
The
|
||||
.Xr ioctl 2
|
||||
interface is fine and this alternative function is rejected in this operating
|
||||
system as it is optional in POSIX 2024.
|
||||
.Ss printf
|
||||
.Xr printf 3
|
||||
is implemented, however floating point formatting is not currently implemented
