SPI_connect

SPI_connect — connect a procedure to the SPI manager

Synopsis

int SPI_connect(void)

Description

SPI_connect opens a connection from a procedure 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 procedures.

If your procedure is already connected,SPI_connect will return the error codeSPI_ERROR_CONNECT. This could happen if a procedure that has calledSPI_connect directly calls another procedure that callsSPI_connect. While recursive calls to theSPI manager are permitted when an SQL command called through SPI invokes another function that usesSPI, directly nested calls toSPI_connect andSPI_finish are forbidden. (But seeSPI_push andSPI_pop.)
