B4R Question Native C: How to use Strings/Chars?

[KMatle]

I'm working on how to use AES with an ESP32. Everything is fine except how to use/return strings (byte arrays/chars). There are some threads but I don't get it.

Code:

Private enc() As Byte ' In Globals

RunNative("InitAES",Null) ' Call

Inline C

#if C
#include <mbedtls/aes.h>

char rstr[50];

void InitAES (B4R::Object* o) {
b4r_main::_enc = rstr;


}
#End if

Error:

b4r_main.cpp:61: error: cannot convert 'char [50]' to 'B4R::Array*' in assignment

I simply need to return "rstr" to "enc"

Try this

b4r_main::_enc->data = rstr;
b4r_main::_enc->length = strlen(rstr);

Try this

b4r_main::_enc->data = rstr;
b4r_main::_enc->length = strlen(rstr);

Thanks. That worked.
