dirname_r?

[Takashi Yamamoto <ya...@midokura.com.INVALID>]

hi,

i'm using FLAT memory model.
i want to use dirname() in my app.
but there seems to be no safe way to use static-buffer returning
functions like this
unless you have very tight control on what you run on your system.
am i correct?
i think it makes sense for nuttx to provide non-standard reentrant versions
of these functions. (say, dirname_r(). macOS has it.)
how do you think?

Many other similar extension(e.g. strtok_r) become standard(POSIX), it's reasonable practice for other functions.
