Discussion

The UNLOAD_OPTION procedure explicitly unloads a previously loaded OPI option. All resources used for the OPI option are freed. OPI options can be loaded explicitly by any PV‑WAVE user using the LOAD_OPTION procedure. These optional modules can be written in C or FORTRAN, and can contain new system functions or other primitives. For detailed information on creating OPI options, see the PV‑WAVE Application Developer’s Guide.

Example

LOAD_OPTION, 'xml' 

LOAD_OPTION, 'image' 

PRINT, '--- Currently loaded modules:'

SHOW_OPTIONS

; Unload the xml module

UNLOAD_OPTION, 'xml'

; Show the options that are still loaded.

PRINT, '--- Currently loaded modules:'

SHOW_OPTIONS
