NAME

6       SPI_connect, SPI_connect_ext - connect a C function to the SPI manager
7

SYNOPSIS

9       int SPI_connect(void)
10
11       int SPI_connect_ext(int options)
12

DESCRIPTION

14       SPI_connect opens a connection from a C function invocation to the SPI
15       manager. You must call this function if you want to execute commands
16       through SPI. Some utility SPI functions can be called from unconnected
17       C functions.
18
19       SPI_connect_ext does the same but has an argument that allows passing
20       option flags. Currently, the following option values are available:
21
22       SPI_OPT_NONATOMIC
23           Sets the SPI connection to be nonatomic, which means that
24           transaction control calls SPI_commit, SPI_rollback, and
25           SPI_start_transaction are allowed. Otherwise, calling these
26           functions will result in an immediate error.
27
28       SPI_connect() is equivalent to SPI_connect_ext(0).
