Intermec ck1 Reference Guide

µClinux System 

• Tool Manager 

• Print support 

•  Find and replace facilities 

•  Package manager, for easy installation of add-on libraries 

For help using the SDK Wizard, see Chapter 1, “Installing and Using the 
SDK.” 

The libraries supported by CK1 are 

µClibc, Nano-X, GDBM, pthread. To 

use these libraries, you need to install the SDK. 

The 

µClibc are developed based on ANSI-C99 and SUSV3.  

The Nano-X version that the CK1 uses is microwindows-0.87. For more 
information, see Chapter 5, “Nano-X APIs.” 

The GDBM is supported by CK1. For the detail description, please refer 
to http://www.mit.edu:8001/afs/athena.mit.edu/project/gnu/doc/html 
/gdbm_toc.html. 

The following content introduces the database named GDBM, which is 
included in the Esfia embedded Linux package. The gdbm is a simple 
database with better performance than ndbm or dbm. The database 
manages the data block with a key value. It provides New/Update, First, 
Next, Fetch, and Count functions. To use the database library, 
gdbmdefs.h and gdbmerrno.h should be included, and the library 
libgdbm.a and libgdbm_compat.a are both required to be linked. 

The function store is to store a data block with a key string. User may use 
this function to create a new record or update an old record. Old record 
with the same key will be replaced with newest data block. 

The function first seeks the current record to the first record. The function 
next seeks the next record. The GDBM does not provide changing record 
number to any record except first record.
