.SH "NAME"
SPI_connect, SPI_connect_ext \- connect a C function to the SPI manager
.SH "SYNOPSIS"
.sp
.nf
int SPI_connect(void)
.fi
.sp
.nf
int SPI_connect_ext(int \fIoptions\fR)
.fi
.SH "DESCRIPTION"
.PP
\fBSPI_connect\fR
opens a connection from a C function invocation to the SPI manager\&. You must call this function if you want to execute commands through SPI\&. Some utility SPI functions can be called from unconnected C functions\&.
.PP
\fBSPI_connect_ext\fR
does the same but has an argument that allows passing option flags\&. Currently, the following option values are available:
.PP
SPI_OPT_NONATOMIC
.RS 4
Sets the SPI connection to be
nonatomic, which means that transaction control calls (\fBSPI_commit\fR,
\fBSPI_rollback\fR) are allowed\&. Otherwise, calling those functions will result in an immediate error\&.
.RE
.PP
SPI_connect()
is equivalent to
SPI_connect_ext(0)\&.
.SH "RETURN VALUE"
.PP
SPI_OK_CONNECT
.RS 4
on success
.RE
.PP
SPI_ERROR_CONNECT
.RS 4
on error
