elosLog: Support format strings

[simone-weiss]

The function is currently defined like

void elosLog(elosEventMessageCodeE_t messageCode, elosSeverityE_t severity, uint64_t classification, const char *logMessage)

Assuming Devs have most experience with functions like printf, syslog, etc.

It would be convenient if format strings would be supported, this would be a quality of live improvement.

void elosLog(elosEventMessageCodeE_t messageCode, elosSeverityE_t severity, uint64_t classification, const char * format, ...)

Hi Simone,

thank you for the suggestion. This sounds really useful I will take this onto our roadmap we have to check when we can integrate this as it is in this from a breaking change.

Probably a "F"-Version of elosLog is a good compromise.

void elosLogF(elosEventMessageCodeE_t messageCode, elosSeverityE_t severity, uint64_t classification, const char * format, ...)
