has anyone produced versions of the BSD functions ftruncate() and sigsetmask() for SysV, in particular for the 3b1? any pointers as to where these could be found would be helpful. alternatively, are there any SysV equivalent approaches?

There is no fully-functional equivalent to "ftruncate()" in any flavor of vanilla S5, which makes it unlikely that anybody's produced a version of them for S5 - the hooks just aren't there. "sigsetmask" also requires a more powerful signal mechanism than existed prior to S5R3; it might be possible to do some or all of "sigsetmask" atop S5R3, but it's not posssible to do it atop the signal mechanism that existed prior to that.

Uhh, no, it isn't, it's "truncate". "ftruncate" is harder, since it
takes a file descriptor, not a path name, as its first argument....scs@lokkur.UUCP (Steve Simmons) (04/24/89)
