Yes, I use a Microsoft Visual Studio compiler, but the full version - not
Express Edition. Just in case I quote the code again ( it's short):
----------------------------------------------------------------------
include "postgres.h"
#include "fmgr.h"
#include "executor/executor.h"
#include "utils/timestamp.h"
#include "utils/builtins.h"
#include "utils/formatting.h"
#ifdef PG_MODULE_MAGIC
PG_MODULE_MAGIC;
#endif
#define GET_TEXT(cstrp) DatumGetTextP(DirectFunctionCall1(textin,
CStringGetDatum(cstrp)))
PG_FUNCTION_INFO_V1(getTimeFromApplication);
Datum
getTimeFromApplication(PG_FUNCTION_ARGS)
{
PG_RETURN_TEXT_P(GET_TEXT("success"));
}
----------------------------------------------------------------------
Preprocessor definitions:WIN32;_DEBUG;_WINDOWS;_USRDLL;C_SYNCTIME_EXPORTS
Postgres 8.3.3 (standard binaries - so built by means of MSVC), WinXP SP2.
Error while using the function in PG - invalid memory alloc request size
4294967293
It seems to me I must change some other options in Configuration Properties -
but I can't guess what exactly...
Or maybe I should use Visual Studio 2005 Express Edition necessarily?
