Good Morning Emiliano-
since postgres is written in 'C'
and Most of us on this list have programmed in C ..although my experience was
'used in last millenia'
if we reference contrib/query/tsearch2/query.c
when you see statements such as
PG_FUNCTION_INFO_V1(tsquery_in);
you are calling a header file at \include\server\fmgr\fmgr.h which is
macro-subbing at
specifically:
#define PG_FUNCTION_INFO_V1(funcname) \
extern Pg_finfo_record * CppConcat(pg_finfo_,funcname) (void); \
Pg_finfo_record * \
CppConcat(pg_finfo_,funcname) (void) \
{ \
static Pg_finfo_record my_finfo = { 1 }; \
return &my_finfo; \
} \
extern int no_such_variable
In any case please feel free to ping us for any questions you might have
It sounds like you have quite a challenge ahead of you
Buena Suerte
Martin-

Subject: Re: [GENERAL] Stored procedures in C
Thanks a lot for the response Andrej!
One of these texts was known for me. But all of them are VERY basic. No one
explains how to do a query and manage results :(
The only one that manage querys is the source code placed at
contrib/tablefunc in the Postgres distribution. But is VERY hard to follow for
me :( I would like to find an intermediate step.
Thanks again
Emiliano

You don't mentioned where else you looked - did you come across these?
