The only possible flag value is \fBSCSI_HBA_CANSLEEP\fR (memory allocation may sleep). .RE .sp .ne 2 .mk .na \fB\fIhba_tran\fR\fR .ad .RS 12n .rt Pointer to a \fBscsi_hba_tran\fR(9S) structure. .RE .SH DESCRIPTION .sp .LP For \fBscsi_hba_tran_alloc()\fR: .sp .LP The \fBscsi_hba_tran_alloc()\fR function allocates a \fBscsi_hba_tran\fR(9S) structure for a \fBHBA\fR driver. The \fBHBA\fR must use this structure to register its transport vectors with the system by using \fBscsi_hba_attach_setup\fR(9F). .sp .LP If the flag \fBSCSI_HBA_CANSLEEP\fR is set in \fIflags\fR, \fBscsi_hba_tran_alloc()\fR may sleep when allocating resources; otherwise it may not sleep, and callers should be prepared to deal with allocation failures. .sp .LP For \fBscsi_hba_tran_free()\fR: .sp .LP The \fBscsi_hba_tran_free()\fR function is used to free the \fBscsi_hba_tran\fR(9S) structure allocated by \fBscsi_hba_tran_alloc()\fR. .SH RETURN VALUES .sp .LP The \fBscsi_hba_tran_alloc()\fR function returns a pointer to the allocated transport structure, or \fBNULL\fR if no space is available. .SH CONTEXT .sp .LP The \fBscsi_hba_tran_alloc()\fR function can be called from user, interrupt, or kernel context. Drivers must not allow \fBscsi_hba_tran_alloc()\fR to sleep if called from an interrupt routine. .sp .LP The \fBscsi_hba_tran_free()\fR function can be called from user, interrupt, or kernel context context. .SH SEE ALSO .sp .LP \fBscsi_hba_attach_setup\fR(9F), \fBscsi_hba_tran\fR(9S) .sp .LP \fIWriting Device Drivers in Oracle Solaris 11.4\fR
