[cfe-dev] StringLiteral API clarification?

[Marcus Johnson via cfe-dev]

Hi guys,

I'm working on extending format string validation, and I was going through the FormatStringLiteral -> StringLiteral -> StringRef 

and I'm just wondering what the following functions mean?

strLen()

getLengthInBytes()

getLength()

size()

What do these functions return?

How do I get the size of a string in CodeUnits or CodePoints?
