Hi all
I don't know if it is the right mailing list, but i was wondering if one could introspect via gdb the content of PGresult.
In my case i got a coredump and when i tried to analyze the core and try to print the content of PGresult i got incomplete type
I'm using libpq-13.3 (installed via libpq-13.3-1.el8_4.x86_64, RHEL8.5). Any help would be appreciated (i'm trying to get the errMesg value of this field)
(gdb) p res
$1 = (PGresult *) 0x7f0718000b80
(gdb) p *res
$2 = <incomplete type>
(gdb) ptype res
type = struct pg_result {
<incomplete type>
} *
(gdb) explore res
'res' is a pointer to a value of type 'PGresult'
Continue exploring it as a pointer to a single value [y/n]: y
The value of '*res' is of type 'PGresult' which is a typedef of type 'pg_result'
The value of '*res' is a struct/class of type 'pg_result' with no fields.
(gdb)
thanks for your hints
