Re: Shared memory in extensions

Hi Thomas, I tried to create a shared segment of size 5 megabytes in the PHP_MINIT_FUNCTION and I had no problems. The situation you described seems as you have called shmctl with IPC_RMID but not everyone had detached from the segment. Then you tried to use shmget and it failed - remove manually the shared memory segment and try again. -- Alexander Feldman Zend Technologies Ltd. phone: +972 3 6139665 ext. 113, fax: +972 3 6139671 http://www.zend.com/ On Mon, 2 Apr 2001, Thomas Wentzel wrote: > Hehe - sorry :) > Errno is set to 43 (Identifier removed (?)) > > > The URL is: > > http://www.humanfactor.com/cgi-bin/cgi-delegate/apache-ML/nh/1999/Jan/0467.html > - enjoy ;) > > Thomas > > Gavin Sherry wrote: > > > > Thomas, > > > > When shmget() fails, it sets errno.
