Database.PostgreSQL.LibPQ.Internal

Description

This module exports the data constructor for the database connection object so that people may create their own foreign bindings to libpq functions that may not exist yet in vanilla postgresql-libpq.

Synopsis

data Connection = Conn !(ForeignPtr PGconn) !(MVar NoticeBuffer)
withConn :: Connection -> (Ptr PGconn -> IO b) -> IO b
data PGconn
data CNoticeBuffer
type NoticeBuffer = Ptr CNoticeBuffer
