Reads string from registry key.
const ARoot: HKey;
const AKey, AName: String;
const ADefault: String = ''
One of predefined HKEY_XYZ constants. Usually it's HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE.
A full absolute path to key.
A name of value to read.
Optional default value.
Actual value from registry key, if it's exists. ADefault value - if there is error (no access, value or key do not exist).
Returned value does not need to be decoded by DecodeConfigValue, because registry can hold exact binary copy of data itself.
This is low-level routine. Use it only to implement your own custom high-level wrapper.
Use ConfigReadString or ConfigWriteString (or their equivalents) to read and write configurations.
