Set and retrieve environment variables in Windows™ environmentsYou might change the settings of environment variables or create new variables to increase the flexibility of an application. Instead of assuming a particular environment configuration, you can define the environment at run time.
The InetLogin structureThe client application in a Windows™ environment can use the InetLogin structure to set dynamically the configuration information that the application needs.

The InetLogin structure

The client application in a Windows™ environment can use the InetLogin structure to set dynamically the configuration information that the application needs.

Important: HCL OneDB™ supports the InetLogin structure for compatibility with earlier versions only. For new development, it is recommended that you use the ifx_getenv() and ifx_putenv() functions instead.

This section provides the following information about InetLogin:

A description of the InetLogin structure, its fields, and header file
The precedence of configuration information that the client application sends when it establishes a connection
