C makes very few assumptions about the operatinf system
as such mkdir isn't an ISO standard... some operting systems don't support
directories....

mkdir() made it into Posix, so it should be availavble on most
platforms that support that sort of behavior.... (eg not available on CP/M)

note also that mkdir will fail if there's already a file with a name like
the directory you want to create, or may fail for other resons too...

 NH> BTW, mkdir() is a standard part of Java, FWIW.

java is differenlty targeted than C.

Bingo! use mkdir().
