INTERFACE LEVEL

Solaris DDI specific (Solaris DDI).

Pointer to the buf(9S) structure.

DESCRIPTION

The scsi_free_consistent_buf() function frees a buffer header and consistent data buffer that was previously allocated using scsi_alloc_consistent_buf(9F).

The scsi_free_consistent_buf() function can be called from user, interrupt, or kernel context.

SEE ALSO

WARNING

The scsi_free_consistent_buf() function will call freerbuf(9F) to free the buf(9S) that was allocated before or during the call to scsi_alloc_consistent_buf(9F).

If consistent memory is bound to a scsi_pkt(9S), the pkt should be destroyed before freeing the consistent memory.
