Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in HCL OneDB™ databases.
DataBlade® API Function ReferenceThe HCL OneDB™ DataBlade® API Function Reference describes the DataBlade® API functions and the subset of functions that the DataBlade® API supports.
Function descriptionsThis section gives comprehensive reference information about the functions that are valid within DataBlade® API modules. It lists the function descriptions in alphabetical order, with syntax, usage information, and return values for the functions.
The mi_stream_tell() functionThe mi_stream_tell() function returns the current seek position of an open stream, relative to the beginning of the stream.

The mi_stream_tell() function

The mi_stream_tell() function returns the current seek position of an open stream, relative to the beginning of the stream.

Syntax

mi_int8 *mi_stream_tell(strm_desc)
   MI_STREAM *strm_desc;

strm_desc: A pointer to a stream descriptor for an open stream.


Valid in client LIBMI application?	Valid in user-defined routine?
No	Yes

Usage

The mi_stream_tell() function obtains the current seek position of the stream that strm_desc references. The stream seek position is the offset for the next read or write operation on the stream. The mi_stream_tell() function returns this seek position as a pointer to an mi_int8 value.

Return values

An mi_int8 pointer: A pointer to the stream seek position, measured in the number of bytes from the beginning of the stream.
NULL: The function was not successful.
