Create $or$ Open the Shared Memory Object:

Function: $sh{m}_o$pen$()$

Purpose: Creates a new shared memory object $or$ opens $an$ existing one identified $by$ a name $in$ the file system.

Set the Size $of$ the Shared Memory Object:

Function: ftruncate$()$

Purpose: Defines the size $of$ the shared memory object $to$ allocate enough memory for data storage.

Map the Shared Memory Object into Process Address Space:

Function: mmap$()$

Purpose: Maps the shared memory object into the virtual address space $of$ the process, allowing $itto$ access and manipulate the shared memory.

Synchronize Access with Synchronization Mechanisms:

Functions: Use mutexes, semaphores, $or$ other synchronization primitives.

Purpose: Ensures coordinated access and modification $of$ shared data among multiple processes $to$ avoid race conditions and maintain data consistency.

Detach and Cleanup $(Optional)$:

Functions: munmap$()to$ detach, $sh{m}_u$nlink$()to$ unlink.

Purpose: Releases the shared memory mapping from the process address space and optionally removes the shared memory object from the file system namespace.
