NAME
SPI_connect, SPI_connect_ext - connect a C function to the SPI manager
SYNOPSIS
int SPI_connect(void)
int SPI_connect_ext(int options)
DESCRIPTION
SPI_connect 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.
SPI_connect_ext does the same but has an argument that allows passing
option flags. Currently, the following option values are available:
SPI_OPT_NONATOMIC
Sets the SPI connection to be nonatomic, which means that
transaction control calls (SPI_commit, SPI_rollback) are allowed.
Otherwise, calling those functions will result in an immediate
error.
SPI_connect() is equivalent to SPI_connect_ext(0).
RETURN VALUE
SPI_OK_CONNECT
on success
SPI_ERROR_CONNECT
on error
