This is a bit off-topic, but I haven't found this information in the freebsd website nor google... and this seems to be the most programmer oriented mailinglist If I have 2 or more different programs using the same shared library... The first program loads the .so at startup and keeps running. My question is that when the second program starts, does it have to load the .so again, or the memory used by the shared library will be shared between all the two programs? I know that different processes started by the same parent share the .so, but I wanna know if completely different programs started by different parents can share the same shared object. For example, if perl/DBI started from the shell, and php/mysql started from apache can share the same libmysqlclient.so in memory. Thanks for any information and sorry for the offtopic
