Access InterSystems IRIS from C programs.
C is a commonly used programming language.
Enables you to access InterSystems IRIS from C programs. You can execute ObjectScript commands and evaluate InterSystems IRIS expressions. The Callin API permits a wide variety of applications. For example, you can use it to create an interface between ObjectScript and an application that presents an integrated menu or GUI. If you gather information from an external device, such as an Automatic Teller Machine or piece of laboratory equipment, the Callin API lets you store this data in an InterSystems IRIS database. Any language that uses the C/C++ calling standard for that platform can invoke the Callin functions.
