Parameter |
Description |
|
Name of variable to test for. |
Notes:
The constants can define platforms at different levels and are not mutually exclusive. For example, on WinNT, the platform returned can be WIN32_X86, WINNT, WIN32, or WINDOWS. Product constants are defined by, and are specific to, the host product (for example Notes, 1-2-3, ESB, and so on). Refer to the product's documentation for a list of product-defined constants.
