They aren't currently supported on Linux kernel.
I, however, heard that Cristopher Rohland
<hans-christoph.rohland@sap.com> has already tried to write
code about POSIX Shared memory. 
I'm also trying the POSIX message queues...
But, they are very under depelopment stage, so you should use
SYSV IPC instead of POSIX IPC functions.
IMHO, porting from POSIX IPC to SYSV IPC may be complicate,
but SYSV IPC already exists, and they are very stable, tested
on Linux for a long time.
