Hello,

GetCurrentDirectory() under linux is obtained via
getcwd(h, 1024)

Unfortunatly this function return a different directory depending whether the program is run typing in consolle or by a double click.
This make a BIG difference if the app run another executable that depends by the "real" current directory, i.e. where the exe file resides.
I wonder if there is a safer and better way under linux to achieve the wanted purpose.

GetCurrentDirectory() returns, as the name says, the current directory, which on most non-windows systems is the directory from where the binary was executed, non where it resides. To obtain the position of the binary, there is GetExeFilePath().

Best regards,
Honza

PS: Also, the current directory can change while the program is running.

Ops... Thank you for this precious info!
It means GetExeFilePath() is what I need for both OS when the position of the executable is important to reach other files.

The change of current directory may happen even under windows?

Sure, but it can change only by direct action of the executable IIRC (calling change dir). Anyway, current directory doesn't depend on executable path at all.
