was the command in delphi for making any IO errors not raise an
exception

namely i am using the mkdir command to make a directory in win32

however if the directory already exists i want the application to
ignore trying to make it and use the existing directory anyway
silently

is there some lazarus equivalent to this?

thanks

Yes, but probably a safer approach is just to check if directory
exists and, if so, don't call mkdir. Turning off exceptions probably
not a good habit.

Thanks.

Couldn't you just use a try finally block to ignore the exception ?

Uses procedure "Forcedirectory" (or forcedirectories)

thanks phil, how do i check if it exists. i know "fileexists" but
didnt realise there was a directory equivalent!

and thanks to all the other guys - if phil's suggestion works, i think
it will be the most "solid" solution

after not being lazy and doing some research it seems you use
"directoryexists".  lol.
