+PR_AttachSharedMemory
+=====================
+
+Attaches a memory segment previously opened with :ref:`PR_OpenSharedMemory`
+and maps it into the process memory space.
+
+
+Syntax
+------
+
+.. code::
+
+   #include <prshm.h>
+
+.. code::
+
+   NSPR_API( void * )
+     PR_AttachSharedMemory(
+        PRSharedMemory *shm,
+        PRIntn flags
+   );
+
+   /* Define values for PR_AttachSharedMemory(...,flags) */
+   #define PR_SHM_READONLY 0x01
+
+
+Parameters
+~~~~~~~~~~
+
+The function has these parameters:
+
+shm
+   The handle returned from :ref:`PR_OpenSharedMemory`.
+flags
+   Options for mapping the shared memory. ``PR_SHM_READONLY`` causes the
+   memory to be attached read-only.
+

+Retrieve the reason for the failure by calling :ref:`PR_GetError` and
