Date: 28 Sep 1994 16:16:40 -0500 Organization: Kansas State University Lines: 14 Message-ID: <36cmfo$hth@matt.ksu.ksu.edu> NNTP-Posting-Host: matt.ksu.ksu.edu X-Newsreader: NN version 6.5.0 #1 (NOV) I was wondering in the standard linux develpment packages implemented a semaphore synchronization call. If not, how do you synchronize two processes to keep them from entering their critical sections at the same time? I haven't installed or used linux yet, but I am going to try soon and would like to know what kind of system calls are available. I have several unix programs that use the semaphore method and I would like to just be able to transfer them to linux and compile them. Neal Howland nhowl...@matt.ksu.ksu.edu

Using named pipes is an elegant method to achieve this. -- "You'll never be the man your mother was!" -- Harald Milz (h...@ix.de) WWW: http://www.ix.de/editors/hm.html iX Multiuser Multitasking Magazine phone +49 (511) 53 52-377 Helstorfer Str. 7, D-30625 Hannover fax +49 (511) 53 52-378 Opinions stated herein are my own, not necessarily my employer's.

There are also the system 5 semaphores which work rather nicely 8) Alan -- ..-----------,,----------------------------,,----------------------------,, // Alan Cox // iia...@www.linux.org.uk // GW4PTS@GB7SWN.#45.GBR.EU // ``----------'`----------------------------'`----------------------------''
