Environment Variables in execve()

[dbraunc]

How can set one Env-Variable (e.g. LD_LIBRARY_PATH) to multiple Paths ? I want to set two different Paths in that Variable (but I don't know how to separate the two paths !).
Then I want to call the execve-function with this environment.
Can anyone help me ?

AFAIK, you can set environment variables to more than one value. It can be done by separating the values by a comma. So in LD_LIBRARY_PATH it would look like this:

LD_LIBRARY_PATH=/usr/lib;/usr/local/lib

Then in execve():

execve("/usr/local/bin/something","-f","LD_LIBRARY_PATH=/usr/lib;/usr/local/lib");

Haven't tested this yet but it is worth a try.

Hope this helps!
