I am writing a installer library in C++. I am having a problem in writing the functions.
1. Create_desktop_Shortcut()
2. Get_application_path()
Can anybody please tell me how to get the path of the current desktop programmatically, and also i didn't find any function to get the path of application, as in windows there is GetModulePath.
I will be thankful if anybdy help me out.

Well, for getting the desktop location, I'm not entirely sure how to definitively do. If you assumed that it was the "Desktop" directory in the home directory, it would be "$HOME/Desktop". The HOME enviroment variable is set to the home directory of the current running user.

For getting the application path, you could try scanning the PATH enviroment variable, searching in each directory in the variable for the application that is being sought. Or you could parse the output of "whereis". I'm pretty sure that "whereis" simply does just that, since you can't run it without an absolute path and without it being in one of the PATH directories.

If this will be done by getting output of a console command; then i think the command should be which :

[root@earth]# whereis ping
ping: /bin/ping /usr/share/man/man8/ping.8.gz
[root@earth]# which ping
/bin/ping

No need to parse something ;-)

Thanks a lot!
that solves my problem.
