Thanks. That and small regex will do just fine.

Yeah. And looks like no function returns FB_MAJOR_VER.

Hope somebody has a nice trick in sleeves.


  isc_get_client_version() returns string with FB_BUILD_SUFFIX as last part.
It have value "Firebird 2.1" for FB 2.1, "Firebird 4.0" for FB 4 and so on.

Hope it helps,

Great!

How could I miss it???

My excitement was short lived. fbclient.dll version 4.0.1.2692 returns 6 and 3 
respectively. :(

Hi *,

Can somebody think of a way to detect whether fbclient supports isc_dpb_utf8_filename? 
For example when calling isc_create_database in .NET provider with "Embedded" I 
need to know whether I can use UTF8 in database path.

On Windows I can check version of the DLL and when version >= 2.5 I can assume 
I'm safe (What happens when I connect using 2.5 to older database?). But on Linux, 
etc. the binary has no such version info in header. Bummer.


from ibase.h:

//
/* Client information functions */
//

void ISC_EXPORT isc_get_client_version ( ISC_SCHAR  *);
int  ISC_EXPORT isc_get_client_major_version ();
int  ISC_EXPORT isc_get_client_minor_version ();

I can also tell everybody that < 2.5 is not supported and happily use 
isc_dpb_utf8_filename (OK, maybe also I need to care about 
isc_spb_utf8_filename.), but that's lame.

For isc_database_info I don't have handle.

I'm kind of missing op_connect phase to get the selected protocol version. :)
