(Feeling a little slow these days)...
The documentation describes what the dbp (array) is supposed to contain. The isc_expand_dpb() function call is supposed to fill it for you. It took me several days to give up on isc_expand_dpb(); it is now anti-recommended. It took me an hour to write my own code to fill in the array myself. Here is a copy and paste of my source code, working for six months now:
char DbParmBuffer[ 256 ];
short DbParmLength;
char * Src;
char * DbPtr;
DbPtr = DbParmBuffer;
*DbPtr++ = isc_dpb_version1;
*DbPtr++ = isc_dpb_user_name;
*DbPtr++ = strlen( DbUserName );
for ( Src = DbUserName;
( *DbPtr = *Src ) != 0;
++DbPtr, ++Src );
// note strings in the buffer don't end with a NUL byte
*DbPtr++ = isc_dpb_password;
*DbPtr++ = strlen( DbPassword );
for ( Src = DbPassword;
( *DbPtr = *Src ) != 0;
++DbPtr, ++Src );
DbParmLength = DbPtr - DbParmBuffer;
