Hi,
I'm implementing a module in pgsql on the server side (Win32 version, but
it's not platform-specific). I need access to a specific file whose name I
know (of course!). I'm trying to use a buffered access though the BufFile
type (header path is 'include/storage/buffile.h').
The problem is that there is only one constructor for data type BufFile
(namely 'extern BufFile *BufFileCreateTemp(bool interXact);'). The other
possible constructors I found were in buffile.c but the only one that
allows me to specify a file is protected by an 'ifdef NOT_USED'.
My questions are:
1- is it possible to have a buffered access to a file initially external
to the database ? If yes, how can I do that ?
2- what is the meaning of the NOT_USED define ? A text search showed it is
used in more than 40 files.
Thanks.
