What is the difference between Delphi library routines IsUNCRooted and IsUNCPath?

Time:09-17

The current documentation of both functions reads very similar to each another:

Both are static members of the same class, with one of them decorated inline, so I wouldn't think they are separate implementations with equivalent functionality you often find across various Delphi classes (although examples within a common class do exist in Embarcadero's standard library).

Specifically, I can't come up with a case where a path is a valid UNC path but not a rooted UNC path. So what does IsUNCRooted even mean?

CodePudding user response:

IsUNCRooted only checks if the parameter starts with an UNC sequence, while IsUNCPath also checks the rest for valid path names. So a valid UNCPath is indeed also UNC rooted, but not always the other way round.
