.SH DESCRIPTION
.sp
.LP
The \fBit_tpg_create()\fR function allocates and creates an \fBit_tpg_t\fR
structure representing a new iSCSI target portal group. The new \fBit_tpg_t\fR
structure is added to the global \fItpg\fR list (\fIcfg_tgt_list\fR) in the
\fBit_config_t\fR structure.
.sp
.LP
The \fBit_tpg_delete()\fR function deletes the target portal group represented
by \fItpg\fR, where \fItpg\fR is an existing \fBit_tpg_t\fR structure within
the global configuration \fIcfg\fR.
.sp
.LP
The \fBit_tpg_free()\fR function deallocates resources associated with an
\fBit_tpg_t\fR structure. If \fItpg\fR->\fInext\fR is not \fINULL\fR, this
function frees all members of the list.
.sp
.LP
Configuration changes as a result of these functions are not instantiated until
the modified configuration is committed by calling
\fBit_config_commit\fR(3ISCSIT).
.SH RETURN VALUES
.sp
.LP
The \fBit_tpg_create()\fR and \fBit_tpg_delete()\fR functions return 0 on
success and an error value on failure.
.SH ERRORS
.sp
.LP
The \fBit_tpg_create()\fR and \fBit_tpg_delete()\fR functions will fail if:
.sp
.ne 2
.na
\fB\fBEBUSY\fR\fR
.ad
.RS 10n
The portal group is associated with one or more targets.
.RE

.sp
.ne 2
.na
\fB\fBEEXIST\fR\fR

.RS 10n
The portal was already configured for another portal group associated with this
target.

\fB\fBEINVAL\fR\fR
