Description
This utility can retrieve information about any module that is currently
loaded into the system. The information that can be requested is:
- raw_interface (list of export/1 and reexport/1)
-
this returns a list of all the export and reexport directives that
occurred in the definition of the module and thus comprise the module's
interface.
- interface (list of export/1)
-
Like raw_interface, but all reexports are replaced by the
actual exports which result from them.
- imports (list of modules)
-
a list of the modules that have been imported as a whole.
- locked (on/off)
-
indicates whether the module is locked or unlocked.
