Yes. - Such an input parameter validation is performed by the
function implementation.

I sent update suggestions because of this function property for two
Linux software modules in the year 2015.

Thanks for your feedback.

A single goto label will look convenient for a while. It will often work
for several use cases.

more software efficiency.

How often do you care for efficient exception handling in the shown
function implementations?
