[lazarus] open file with associated application

[Melchiorre Caruso]

Hi, could anybody explain to me how to "open a files with associated application"? With Delphi I use ShellExecute function:   ShellExecute (0, 'open', PChar (FileName), nil, PChar (PathName), SW_SHOW); but I search a function, that works on both OS (Linux and Windows); Thank you --- Melchiorre Caruso
