Description
Mythzmserver doesn't support memory mapped Zoneminder installations, which have become the default in recent releases (1.24.4). For instance, after an upgrade to Ubuntu Oneiric, the zoneminder apt package is compiled with mmap support by default, which no longer interoperates with mythzmserver out of the box.
As a workaround, the Mythzoneminder wiki entry is clear about this and suggests the recompile and installation of Zoneminder from source using shared memory options, which should work fine.
Instead, I'd like to suggest the attached patch to make mythzmserver compatible with the memory mapping method, while maintaining the original shmget() functionality as a failover.
Tested using branch fixes/0.24 and Zoneminder 1.24.4 (Ubuntu repository packages).

mythzoneminder: Add support for mmap
Newer versions of ZoneMinder? can use both shm and mmap for it's inter process
shared memory this updates mythzmserver to be able to read the live camera
images and status using both methods. Closes #10174.
Note: Only tested to make sure shm still works.
