SPI_commit, SPI_commit_and_chain — commit the current transaction
void SPI_commit(void)
void SPI_commit_and_chain(void)
SPI_commit
commits the current transaction. It is approximately equivalent to running the SQL command COMMIT
. After the transaction is committed, a new transaction is automatically started using default transaction characteristics, so that the caller can continue using SPI facilities. If there is a failure during commit, the current transaction is instead rolled back and a new transaction is started, after which the error is thrown in the usual way.
SPI_commit_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 COMMIT AND CHAIN
.
These functions can only be executed if the SPI connection has been set as nonatomic in the call to SPI_connect_ext
.
