.SH DESCRIPTION
.sp
.LP
The \fBscf_entry_create()\fR function allocates a new transaction entry handle.
The \fBscf_entry_destroy()\fR function destroys the transaction entry handle.
.sp
.LP
The \fBscf_entry_handle()\fR function retrieves the handle associated with
\fIentry\fR.
.sp
.LP
A transaction entry represents a single action on a property in a property
group. If an entry is added to a transaction using
\fBscf_transaction_property_new\fR(3SCF),
\fBscf_transaction_property_change\fR(3SCF), or
\fBscf_transaction_property_change_type\fR(3SCF), \fBscf_entry_add_value()\fR
can be called zero or more times to set up the set of values for that property.
Each value must be set and of a compatible type to the type associated with the
entry. When later retrieved from the property, the values will have the type of
the entry. If the values are committed successfully with
\fBscf_transaction_commit\fR(3SCF), they will be set in the order in which they
were added with \fBscf_entry_add_value()\fR.
.sp
.LP
The \fBscf_entry_reset()\fR function resets a transaction entry, disassociating
it from any transaction it is a part of (invalidating the transaction in the
process), and disassociating any values that were added to it.
.sp
.LP
The \fBscf_entry_destroy_children()\fR function destroys all values associated
with the transaction entry. The entry itself is not destroyed.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBscf_entry_create()\fR returns a new
\fBscf_transaction_entry_t\fR. Otherwise, it returns \fINULL\fR.
.sp
.LP
Upon successful completion, \fBscf_entry_handle()\fR returns the handle
associated with the transaction entry. Otherwise, it returns \fINULL\fR.
.sp
.LP
Upon successful completion, \fBscf_entry_add_value()\fR returns 0. Otherwise,
it returns -1.
