Some ObjectARX applications use large amounts of system memory. If you
are finished using an application and want to remove it from memory, use
the Unload option of ARX.
You can also load an ObjectARX application with the arxload AutoLISP
function. The syntax for the arxload function is almost identical to that of
the load function used with AutoLISP files. If the arxload function loads the
ObjectARX program successfully, it returns the program name. The syntax for
the arxload function is as follows:
(arxload filename [onfailure])
The two arguments for the arxload function are filename and onfailure. As
with the load function, the filename argument is required and must be the
complete path name description of the ObjectARX program file to load. The
onfailure argument is optional and typically not used when you load
ObjectARX programs from the command prompt. The following example
loads the ObjectARX application myapp.arx.
(arxload "myapp")
As with AutoLISP files, AutoCAD searches the library path for the specified
file. If you need to load a file that is not in the library path, you must provide
the full path name description of the file.
NOTE When specifying a directory path, you must use a slash (/) or two backslashes
(\\) as the separator, because a single backslash has a special meaning in AutoLISP.
Attempting to load an application that has previously been loaded results in
an error. Before using arxload you should use the arx function to check the
currently loaded applications.
To unload an application with AutoLISP, use the arxunload function. The
following example unloads the myapp application.
(arxunload "myapp")
Using the arxunload function not only removes the application from memory
but also removes the command definitions associated with that application.
