System V ftruncate()

[glenn.theobald]

I am looking for a System V emulation of the BSD ftruncate().

I saw one somewhere on the net over a year ago (possibly 1988) 
and did not save a copy.

Would the original poster, or some other kind soul who kept a copy
of the article forward it to me.

The enulation used the reserved (and undocumented) F_FREESP fnctl
call.

Thanks,
