Thread overview
creating a temporary fifo (tmpfile but for fifo)
February 12
* std.stdio.tempfile creates an (unnamed) File. How do I create a temporary
fifo instead?
my workaround is to use tempnam but docs says it's not recommended (
http://man7.org/linux/man-pages/man3/tempnam.3.html)

* could we allow specifying a directory name for tmpfile?

I believe the recommended function for this is mkstemp. [1]

Yes, using mkdtemp. [2]

Note that these functions are part of POSIX but not C99, and are not included in D's core.stdc module.

They're declared in core.sys,posix.stdlib. -- Andrei

Thanks for the tip. Is this module documented anywhere? I can't find it in the dlang.org docs.

For some reason it doesn't seem to be on the website, but the source is here to read: https://github.com/dlang/druntime/blob/master/src/core/sys/posix/stdlib.d

Mkstemp creates a regular file, not a fifo

I meant adding a D api to add a temp file rooted under a specified directory; the C api's allow that but not tempfile
