[erlang-questions] Using erl_call
Mon Feb 18 13:27:51 CET 2008
Of course you need to have the correct path setup in order to find erl_call.
But I think it is really questionable why you should execute erl_call
at all from a C-node as you call it.
A C-node is for me a C-program communicationg with other Erlang-nodes
and C-nodes using the Erlang distribution Protocol. The C-node is
implemented with help of the ei and erl_interface library functions
which are available in the erl_interface
Erl_call is a C-program that acts as a temporary short lived C-node. Erl_call
is written using the erl_interface functions mentioned above and was originally
meant to be an example of how to use these functions to implement a C-node.
So if you already have a C-node you don't need to execute erl_call. You can
look at the erl_call source code and do something similar in your own C-node
if you have not already implemented functionality for invoking a function on
an Erlang-node from a C-node.
