24/02/2021 radare2 5.1.1 1 @ windows-x86-64 git.5.1.1 commit: 7516c079f0e903551574934b3ae428a5e907a101 build: Thu 02/11/2021__ 9:40:53.69

Windows 10 Education 10.0.19041 Build 19041

1.5.3 (r2pipe version)

## Description

When the included qt code (example r2pipe usage code from git) is run from Qt the following error occurs:

10:38:53: Starting C:\Users\KEHOEJ\Desktop\r2PipeCode\radare2-r2pipe-master\build-r2pipe-Desktop_Qt_6_0_1_MinGW_64_bit-Debug\debug\r2pipe.exe ...
Invalid parameter passed to C runtime function.

(Exception thrown at line 12 of r2pipe.cxx)

<!-- Describe the issue and what would you expect to see -->
I am unfamiliar with the Windows Environment (a linux user) so I am not sure if this is a simple configuration error on my part or if something missing from the r2pipe installation.
I have only installed the binaries for radare2, not compiled from source, and am assuming the r2pipe is included as part of that binary.
Do I have to manually set the two environment variables? (R2PIPE_IN, R2PIPE_OUT)

Thanks,
Joseph.
## Test

<!-- Provide an example to reproduce the issue -->

Those variavkes are set by r2. This program must be executed from the r2 shell like this:

$ radare2 -i r2pipe-program.exe foo.exe

or

$ radare2 foo.exe
> #!pipe r2pipe-program.exe
