@ ATT
Calling this function with defaulted arguments rMaybeFileHdl = Link ( ) and
bCheckFileExists = true often leads to results that are not intended :
Whenever the given rTheBaseURIRef is a file URL , the given rTheRelURIRef is
relative , and rTheRelURIRef could also be smart - parsed as a non - file URL
( e . g . , the relative URL " foo / bar " can be smart - parsed as " http : //foo/bar"),
then SmartRel2Abs called with rMaybeFileHdl = Link ( ) and bCheckFileExists =
true returns the non - file URL interpretation . To avoid this , either pass
some non - null rMaybeFileHdl if you want to check generated file URLs for
existence ( see URIHelper : : GetMaybeFileHdl ) , or use bCheckFileExists = false
if you want to generate file URLs without checking for their existence .
