NAME
sqlbox_trans_commit,
sqlbox_trans_rollback —
end a database transaction
LIBRARY
library “sqlbox”
SYNOPSIS
#include
<stdint.h>
#include <sqlbox.h>
int
sqlbox_trans_commit(struct sqlbox
*box, size_t srcid, size_t
id);
int
sqlbox_trans_rollback(struct sqlbox
*box, size_t srcid, size_t
id);
DESCRIPTION
The
sqlbox_trans_commit()
and
sqlbox_trans_rollback()
functions close a transaction identified as non-zero
id previously opened with the
sqlbox_trans_immediate(3) family on source
srcid as returned by
sqlbox_open(3). If
srcid is zero, the last-opened database is used.
These functions differ in that
sqlbox_trans_commit()
will commit all statements subsequent to beginning the transaction and
sqlbox_trans_rollback()
will discard them.
It is an error to sqlbox_close(3) a database without first rolling back or committing open transactions.
SQLite3 Implementation
Runs sqlite3_exec(3) using the COMMIT or
ROLLBACK statements with the type depending on the
invocation. Randomly backs off on return of
SQLITE_BUSY, SQLITE_LOCKED,
or SQLITE_PROTOCOL, and returns failure on anything
else other than SQLITE_OK.
RETURN VALUES
Returns zero if communication with box fails. Otherwise, returns non-zero.
If ending the transaction fails (not open, different transaction already open, source not found, database errors, id or srcid are zero), subsequent box access will fail. Use sqlbox_ping(3) to check explicitly.
If these functions fail, box is no longer accessible beyond sqlbox_ping(3) and sqlbox_free(3).
