DLIS Library


DLIS Reader is a dynamic-link library for reading DLIS (RP66) files. It exposes a set of functions by which an application can easily read required data.

The library reads data into a tree-shaped structure as it is shown in DlisBrowser program. The user application navigates through the tree with functions provided by the library. Each node in the tree represents a DLIS logical record.

Each EFLR encapsulates a table of information. The rows of the table represent Objects, and the columns of the table represent Attributes of the Objects. At the beginning of the table there is a Template that defines the columns. DLIS library provides functions for access to Template, Objects and their Attributes.

IFLR records contain log data, its structure defined by EFLR. DLIS library provides functions for reading and decoding data written in different Representation Codes used in DLIS specification.

Version 1.3: The prototypes of functions Iflrdata ans IflrDataVal are modified to make them more secure.
