Determines whether a separate-namespace VLX is currently loaded
Supported Platforms: Windows, Mac OS, and Web
Signature
(vl-vlx-loaded-p appname)
- appname
-
Type: String
Name of a VLX application.
Return Values
Type: T or nil
T if the application is loaded, nil if it is not loaded.
Remarks
VLX files are supported on Windows only.
Note: This function is supported on Mac OS and Web, but does not affect the program.
Examples
Check to see if the vlxns application is loaded in its own namespace:
(vl-vlx-loaded-p "vlxns") nil
The application is not loaded in its own namespace.
Now load vlxns:
(load "vlxns.vlx") nil
Check to see if the vlxns application loaded successfully:
(vl-vlx-loaded-p "vlxns") T
This example assumes vlxns was defined to run in its own namespace. If the application was not defined to run in its own namespace, it would load into the current document's namespace and vl-vlx-loaded-p would return nil.
