pktp
Pointer to a scsi_pkt(9S) structure.
The scsi_destroy_pkt() function releases all necessary resources,
typically at the end of an I/O transfer. The data is synchronized to
memory, then the DMA resources are deallocated and pktp is freed.
The scsi_destroy_pkt() function may be called from user, interrupt,
or kernel context.

#include <sys/scsi/scsi.h>
void scsi_destroy_pkt(struct scsi_pkt *pktp);
INTERFACE LEVEL
illumos DDI specific (illumos DDI).
PARAMETERS
pktp
Pointer to a scsi_pkt(9S) structure.
DESCRIPTION
The scsi_destroy_pkt() function releases all necessary resources,
typically at the end of an I/O transfer. The data is synchronized to
memory, then the DMA resources are deallocated and pktp is freed.
CONTEXT
