[erlang-bugs] system_info(nif_version) does not work

[Daniel Goertzen]

The documentation at...

http://www.erlang.org/doc/man/erlang.html#system_info-1

... says I can get nif version information with
erlang:system_info(nif_version).  This does not work.  See output below:



$ erl
Erlang/OTP 17 [erts-6.0.1] [source-deacab9] [64-bit] [smp:3:3]
[async-threads:10] [hipe] [kernel-poll:false]

Eshell V6.0.1  (abort with ^G)
1> erlang:system_info(nif_version).
** exception error: bad argument
     in function  erlang:system_info/1
        called as erlang:system_info(nif_version)
2>



I need nif version information because I am looking at NIF modules written
in Rust.  I will run a short escript to collect config information for the
Rust build.  As a work around I will look at other version information
available though system_info() and make inferences about the NIF
major/minor numbers.
