SPI_rollback
SPI_rollback
SPI_rollback, SPI_rollback_and_chain - abort the current transaction
Synopsis
void SPI_rollback(void)
void SPI_rollback_and_chain(void)
Description
SPI_rollback
rolls back the current transaction. It
is approximately equivalent to running the SQL
command
ROLLBACK
. After the transaction is rolled back,
a new transaction is automatically started using default transaction
characteristics, so that the caller can continue using SPI facilities.
SPI_rollback_and_chain
is the same, but the new
transaction is started with the same transaction
characteristics as the just finished one, like with the SQL command
ROLLBACK AND CHAIN
.
These functions can only be executed if the SPI connection has been set as
nonatomic in the call to
SPI_connect_ext
.
