SAP provides optional platform-specific CPI-C libraries (CPI-C Subsets) for workstations, which you can use for the development of communications programs in the C language.

You can use these libraries to create "more portable" communications programs. This allows communication between SAP systems and external systems, which support CPI-C. The following communications options are available:

• R/3 « C program
• R/2 « C program

These libraries implement the calls of the CPI-C Starter Set, parts of the Advanced Function Calls and SAP-specific calls.

The file cpic.readme contains up-to-date information on the delivered files and using the example programs.

The following files are available:

• Header file for CPI-C
• Development libraries:

• in ABAP
• in C

• Example of a side info file
