scsi_hba_tran_alloc(9F) Kernel Functions for Drivers scsi_hba_tran_alloc(9F)
NAME
scsi_hba_tran_alloc, scsi_hba_tran_free - allocate and free transport structures
SYNOPSIS
#include <sys/scsi/scsi.h>
scsi_hba_tran_t *scsi_hba_tran_alloc(dev_info_t *dip, int flags);
void scsi_hba_tran_free(scsi_hba_tran_t *hba_tran);
INTERFACE LEVEL
Solaris architecture specific (Solaris DDI).
PARAMETERS
dip Pointer to a dev_info structure, defining the HBA driver instance.
flag Flag modifiers. The only possible flag value is SCSI_HBA_CANSLEEP (memory allocation may sleep).
hba_tran Pointer to a scsi_hba_tran(9S) structure.
DESCRIPTION
For scsi_hba_tran_alloc():
scsi_hba_tran_alloc() allocates a scsi_hba_tran(9S) structure for a HBA driver. The HBA must use this structure to register its transport
vectors with the system by using scsi_hba_attach_setup(9F).
If the flag SCSI_HBA_CANSLEEP is set in flags, scsi_hba_tran_alloc() may sleep when allocating resources; otherwise it may not sleep, and
callers should be prepared to deal with allocation failures.
For scsi_hba_tran_free():
scsi_hba_tran_free() is used to free the scsi_hba_tran(9S) structure allocated by scsi_hba_tran_alloc().
RETURN VALUES
scsi_hba_tran_alloc() returns a pointer to the allocated transport structure, or NULL if no space is available.
CONTEXT
scsi_hba_tran_alloc() can be called from user or interrupt context. Drivers must not allow scsi_hba_tran_alloc() to sleep if called from an
interrupt routine.
scsi_hba_tran_free() can be called from user or interrupt context.
