.SH "NAME"
SPI_start_transaction \- start a new transaction
.SH "SYNOPSIS"
.sp
.nf
void SPI_start_transaction(void)
.fi
.SH "DESCRIPTION"
.PP
\fBSPI_start_transaction\fR
starts a new transaction\&. It can only be called after
\fBSPI_commit\fR
or
\fBSPI_rollback\fR, as there is no transaction active at that point\&. Normally, when an SPI\-using procedure is called, there is already a transaction active, so attempting to start another one before closing out the current one will result in an error\&.
.PP
This function can only be executed if the SPI connection has been set as nonatomic in the call to
\fBSPI_connect_ext\fR\&.
