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 PR_OpenSharedMemory.
flags
Options for mapping the shared memory. PR_SHM_READONLY causes the memory to be attached read-only.
