I found the declaration for function GetAppConfigDir in osutilsh.inc but
I cannot find the actual function (I am looking in the wrong file).
If you search the function by clicking on the identifier in Lazarus
while pressing "Ctrl" you should be able to use "Ctrl + Shift + Down" to
find the declaration.
Alternatively you can search the directory "%lazarus%\fpc\%version%\rtl"
to find the implementation (might be some file in the win or win32
directory).
Function GetAppConfigDir(Global : Boolean) : String;
Function GetAppConfigFile(Global : Boolean) : String;
Function GetAppConfigFile(Global : Boolean; SubDir : Boolean) : String;
What is the "Global : Boolean" parameter that it takes? Can someone
please give me an example as to how it is called?
If global is true the system's configuration directory is returned, if
false the current user's directory.
E.g.:
Windows 7:
GetAppConfigDir(True):
C:\ProgramData\AppName
GetAppContigDir(False):
C:\Users\Sven\AppData\Local\AppName (or Roaming, I haven't tested, to be
honest)
Linux:
GetAppConfigDir(True):
/etc/AppName
GetAppConfigDir(False):
/home/sven/.config/AppName
When you use GetAppConfigFile instead, AppName.cfg is returned instead
of AppName.
