<cIniFile>.SetKey error

[DirectuX]

If SetKey fails, it doesn't return an error.

In the example below, setkey always return defaultDBFilename string, even if iniFilename is readonly and the key is not stored.
Expected : setkey return an error code

Uses "File"

#Region "Constants"

Const iniFilename as string = "LM.ini"
Const defaultDBFilename as string = "LM_DB.sql"

#EndRegion

Function Main() As Long
if (not resetINI) Then
printl "error"

end Function

Function resetINI() as Boolean

Return TRUE
