Hello,
I'm (trying to) write a C function to search in array. The array is of
user-defined type (time interval, start and end minute of the day, and
start and end days of the week):
struct tzone {
int begday, endday, begmin, endmin;
int key;
};
(n1: i know begday and endday could be chars but i really hate that memory
alignment GCC does to my structs (and don't want to mess with
__attributes__))
(n2: the type is registered and there are functions tzone_in, tzone_out)
The problematic function should search for a tzone which includes a given
DATETIME.
I have PostrgeSQL 7.0.2 and have read most of the documents for
programming C functions postgresql. There is a table which describes how
sql types are named in C, and I can se DateTime * (structure?) for the
DATETIME type, defined in c.h and/or postgresql.h... but there is no
DateTime anywhere in the source :/
And there is no help about handling arrays from C.
Do I have to look deeper in the docs? Or should I browse the source? Or
there is easier way to implement this..
Sorry for the 'english' :)
Players win and Winners play
Have a lucky day
