From 024ad413bd20219e92c7642e4c29689886bf96ce Mon Sep 17 00:00:00 2001 From: Steve Vinoski Date: Fri, 17 Oct 2014 15:50:41 -0400 Subject: Clarify docs for driver_async() return value The documentation for driver_async() still referred to the return value of the function as a "handle", which is no longer meaningful since driver_async_cancel() was deprecated and removed. Modify the documentation to simply indicate that the driver_async() return value will be -1 if it fails. --- erts/doc/src/erl_driver.xml | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/erts/doc/src/erl_driver.xml b/erts/doc/src/erl_driver.xml index 4a1aab75c7..77fc906aca 100644 --- a/erts/doc/src/erl_driver.xml +++ b/erts/doc/src/erl_driver.xml @@ -2033,7 +2033,8 @@ ERL_DRV_MAP int sz entry function is called.
