Memory allocation OpcUa_SnPrintfA

[JeromeBos]

I can't find any documentation on the function OpcUa_SnPrintfA. Does it allocate memory like 'asprintf' or do I still need to explicitely allocate memory?

Hello,

The macro is directly mapped onto the function snprintf, you need to allocate the needed buffer by yourself (see http://www.cplusplus.com/reference/cstdio/snprintf/).

Thanks for the answer.

Fortunately I also discovered the UaProvider_CustomProvider_NodeIdCreate() function which also handles allocation and does pretty much what I needed.
