[erlang-questions] old module

[József Bérces]

Is there any way to tell if an old version of the module already exists? The return value of code:delete/1 tells that, but that is too late, I would like to know in advance that the module needs purge.

 

Thanks,

Jozsef

erlang:check_old_code(Module) -> boolean()

Types:

Module = atom()

Returns true if the Module has old code, and false otherwise.

(How did I find this? -
> cd <src>/lib/kernel/src
> grep purge *.erl

I found it around line 1401 of code_server.erl

(it's also in the erlang manual page :-)

)
