SPI_rollback, SPI_rollback_and_chain — abort the current transaction
void SPI_rollback(void)
void SPI_rollback_and_chain(void)
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
.
