Memory Segment Rebind
The rebind operation releases the current backing store for an export segment. After releasing the current backing store for an export segment, the rebind operation allocates a new backing store. The application must first obtain a new virtual memory allocation for the segment. This operation is transparent to importers of the segment.
Note –
The application has the responsibility of preventing access to segment data until the rebind operation is complete. Retrieving data from a segment during rebinding does not cause a system failure, but the results of such an operation are undefined.
int rsm_memseg_export_rebind(rsm_memseg_export_handle_t memseg, void *vaddr, offset_t off, size_t size);
Return Values: Returns 0 if successful. Returns an error value otherwise.
