\addtogroup cqdb_reader CQDB Reader API @{

The CQDB reader API provides a read access to the database whose memory image is loaded on a memory block. The memory-passing interface has several advantages. Firstly, one can choose an efficient way for their application to load a database image to a memory block, e.g., to read the whole image from a file, to use the Memory Mapped File (mmap) API, etc. Secondaly, one can design the file format freely only if the memory block for a database is extracted from the file.

The most fundamental operation on the CQDB reader API is forward lookup through the use of cqdb_to_id() function, which retrieves integer identifiers from strings. Reverse lookup (retrieving strings from integer identifiers) with cqdb_to_string() function is not supported if the database has been created with ::CQDB_ONEWAY flag.
