- `O_DIRECTORY` useful for stat'ing (hint on UNIX but required on NT)

Returns cellular dimensions of pseudoteletypewriter display.

unix.tmpfd()

├─→ fd:int

|

|

Returns file descriptor of open anonymous file.
|
||||
|
||||
This creates a secure temporary file inside `$TMPDIR`. If it isn't
|
||||
defined, then `/tmp` is used on UNIX and GetTempPath() is used on
|
||||
the New Technology. This resolution of `$TMPDIR` happens once in a
|
||||
ctor, which is copied to the `kTmpDir` global.
|
||||
|
||||
Once close() is called, the returned file is guaranteed to be
|
||||
deleted automatically. On UNIX the file is unlink()'d before this
|
||||
function returns. On the New Technology it happens upon close().
|
||||
|
||||
On the New Technology, temporary files created by this function
|
||||
should have better performance, because `kNtFileAttributeTemporary`
|
||||
asks the kernel to more aggressively cache and reduce i/o ops.
