This tutorial will take you through the basic use of the c-treeACE C Database API.

Like all other examples in the c-tree tutorial series, this tutorial simplifies the creation and use of a database into four simple steps: Initialize(), Define(), Manage(), and You’re Done() !

Tutorial #1: Introductory - Simple Single Table

We wanted to keep this program as simple as possible. This program does the following:

• Initialize() - Connects to the c-treeACE Database Engine.
• Define() - Defines and creates a "customer master" (custmast) table/file.
• Manage() - Adds a few rows/records; Reads the rows/records back from the database; displays the column/field content; and then deletes the rows/records.
• Done() - Disconnects from c-treeACE Database Engine.

Note our simple mainline:

/*

 * main()

 *

 * The main() function implements the concept of "init, define, manage

 * and you're done..."

 */

#ifdef PROTOTYPE

NINT main (COUNT argc, pTEXT argv[])

#else

NINT main (argc, argv)

COUNT argc;

TEXT argv[];

#endif

{

   Initialize();

   Define();

   Manage();

   Done();

   printf("\nPress <ENTER> key to exit . . .\n");

#ifndef ctPortWINCE

   getchar();

#endif

   return(0);

}

We suggest opening the source code with your own editor.
