Obtaining usernames in MariaDB UDFs


Hello guys,

I am building a set of MariaDB UDFs that require to know a name of a user who called them in each and every call. Users should not be able to pretend as someone else, hence usernames as an argument cannot be used.

I compile UDFs against MariaDB headers and I was able to obtain the current_thd, but the security_ctx pointer inside is NULL.

Could somebody give me a hint what I am doing wrong?

Thank you for your answers!

Best regards,
Denis Scherbakov
