Hi,

I have a custom application (EMA C++ based) sending a post request containing a field value as follows:

<fieldEntry fieldId="393" data="4154 3030 3030 3338 3338 3634 00"/>

The definition of the field in concern is as follows:

OFFCL_CODE "OFFICIAL CODE" 78 NULL ALPHANUMERIC 12 RMTES_STRING 12

The length of the string is 12, but the payload contains 13 bytes, because of the null terminating character.

I'm quite sure I am using the EMA library in an incorrect way, would you please confirm?

My approach is as follows:

• emaBuff is of type refinitiv::ema::access::EmaBuffer
• value is of type refinitiv::ema::access::EmaString
• res is of type refinitiv::ema::access::FieldList

emaBuff.append(value.c_str(), value.length() + 1);
res->addRmtes(393, emaBuff);

From the EMA samples, I see that EMABuffer is built in different ways, so I'm not sure about the correct one. Example:

Elektron-SDK-1.3.0.L1.linux\setup\Cpp-C\Ema\TestTools\QATools\Series100Provider100-ProvFunc-002\IProvider.cpp, line 139

EmaBuffer("5", 2)

In other cases (the majority), the length passed to the buffer is the string length without the null terminating character.

Thanks

Best Regards,

Paolo
