How to retrieve metadata of prepared statement parameter using OCI calls

Hi All,
I am using Oracle 10g release2.
To execute Insert statement function OCIStmtPrepare() is used.
e.g “INSERT INTO BulkInsertTable(IndexName) VALUES(:M)”.
Now, I want to get the metadata(say its datatype, length, etc) of place holder :M programatically. Is there any such method in OCI? Can OCIParamGet() function be of any help for the above said problem.
Need help to proceed further.

Thanks and regards
