4.4.3 Choosing a client definition
You specify the path of the client definition file in the ClientDefPath argument of the a_rdb_SQLAllocConnect() CLI function. If you create multiple client definitions, you can choose the appropriate file when you allocate a connection handle.
If the ClientDefPath argument is omitted, %ADBCLTDIR%\conf\client.def# is assumed. For details about a_rdb_SQLAllocConnect(), see 19.2.1 a_rdb_SQLAllocConnect() (allocate a connection handle).
#: For an HADB client for Linux, $ADBCLTDIR/conf/client.def is assumed.
