Usage Notes
Consider the following when specifying File Close parameters:
Requirements – A File Close function is required when the Reqtype field of the pmiCmdBlock_t structure is either:
pmiPIDMOptClose
pmiPIDMOptCloseR
Removing and Releasing Media – If Reqtype is pmiPIDMOptCloseR, then an Access Module must also release and remove any associated removable media,
such as dismounting a tape from a drive.
