[Python-Dev] mknod for posixmodule

[Gustavo Niemeyer]

People,

we need support for mknod() in python mode. This makes possible
for python modules like tarfile.py to create special nodes.

The first option is of course adding a plain mknod(), with similar
parameters to that found in the C interface, like other examples 
we have in the module. The closest interface would be something
like:

mknod(filename, mode, major, minor)

But the mode parameter, like in the C interface, may be or'ed with
S_IFREG, S_IFCHR, S_IFBLK, S_IFIFO. That seems unpythonic. The
other option that comes to my mind is:

mknod(filename, mode, type, major, minor)

That would make more explicit the need for type. OTOH, we already
have in the library functions for creating fifos and regular
files (S_IFIFO and S_IFREG). So there's another option:

mkblkdev(filename, mode, major, minor)
mkchrdev(filename, mode, major, minor)

What do you think?
