I just finished the DOSish part of ioctl() and will put it
on 
ftp://ftp.lstm.ruhr-uni-bochum.de/pub/djgpp/ioctl.zip
this afternoon (CEST).
It includes support for all Int 0x21/AH=0x44 calls for
AL < 0x12 in a quite easy to uses way. Other functions
can be supported by macros.
The UNIXish part currently does what the not so naive
UNIX-C programmer would expect from a DOS environment:
It return -1 and sets errno. 

WARNING:
ioctl() functions usually work pretty close to the hardware,
involve real mode DOS and _can_ easily wipe out your
harddisk. Better check the source to see if I missed something.
You have been warned.
