Yes, the standard sysV programming interface to shm (which linux uses) goes
through the routines shmget(), shmctl(), shmat() and shmdt(). All use unique
32 bit identifiers as "names" for shared memory regions.

Mint does it a bit more unix like, ie mapps shared memory regions to files
in the filesystem. But I think one could easily write an emulation of the
sysV routines using Mint shm, but not the other way round.
