Обсуждение: C function to send an email in PostgreSQL
Dear all,
I want to create a function to send an email. I pass to the function two arguments: the email to send, and the text
to send.
First, I tried with pointers to char. It worked when I just create a
function called "sendemail()" with no arguments and set inside the text and
the email arguments.
When I read some more documentation about how to use strings in PostgreSQL,
I discovered that I have to use the text type in my C program I just try it
but
although it worked before, now I doesnt work.
This is what I have tried:
#include <stdio.h>
#include "postgres.h"
int sendemail(text *email,text *message)
{
char string_tosend [300];
sprintf(string_tosend,"echo \"%s\" >/tmp/mailtmp.txt
\n",VARDATA(message));
system(string_tosend);
sprintf(string_tosend,"mail -s \"message from PostgreSQL\" %s
</tmp/mailtmp.txt \n",VARDATA(message));
system(string_tosend);
system("rm /tmp/mailtmp.txt");
return 0;
}
and then in the back-end of PostgreSQL and I declared
CREATE FUNCTION sendemail(text,text)
RETURNS int4
AS '/home/postgres/libpginvuimail.so'
LANGUAGE 'c';
and then SELECT sendemail('postgres','test from backend');
and it didnt work. What am I doing wrong?
I have being testing and I guess is something to do with the text data type
and how to use it within a C program.
Many thanks in advance
Miguel
