* devDescriptor [OPAQUE]
|
|
* devDescriptor is a file descriptor for unix RM clients, but a void

|
* pointer for windows RM clients. It is transparent to RM clients i.e. RM's
|
|
* user-mode shim populates this field on behalf of clients.
|
|
*
|
|
* Notes:
|
|
* - Imported fabric memory handles not supported.
|
|
* - No MIG support.
|
|
* - If 'numHandles' and 'index' overlap with a prior call, the newer call's
|
|
* RM handles will overwrite the attached handles from the previous call.
|
|
* This overlapping behavior can also be used to detach a handle by setting
|
|
* the appropriate object in 'handles' to 0.
