* Fix select on fifos.Alfred Perlstein2002-01-141-1/+4
| | | | | | | | | | | | | | | | Backout revision 1.56 and 1.57 of fifo_vnops.c. Introduce a new poll op "POLLINIGNEOF" that can be used to ignore EOF on a fifo, POLLIN/POLLRDNORM is converted to POLLINIGNEOF within the FIFO implementation to effect the correct behavior. This should allow one to view a fifo pretty much as a data source rather than worry about connections coming and going. Reviewed by: bde Notes: svn path=/head/; revision=89376

* Add support for poll(2) on files. vop_nopoll() now returns POLLNVALGarrett Wollman1997-12-151-1/+13
| | | | | | | | | | | | | | | | | | | | | | if one of the new poll types is requested; hopefully this will not break any existing code. (This is done so that programs have a dependable way of determining whether a filesystem supports the extended poll types or not.) The new poll types added are: POLLWRITE - file contents may have been modified POLLNLINK - file was linked, unlinked, or renamed POLLATTRIB - file's attributes may have been changed POLLEXTEND - file was extended Note that the internal operation of poll() means that it is impossible for two processes to reliably poll for the same event (this could be fixed but may not be worth it), so it is not possible to rewrite `tail -f' to use poll at this time.
