SysUtils contains only GetEnvironmentVariable, but not Set...
That's not how it works on Unix/Linux.
You must always set up environment variables before a program starts.
When starting a process, the environment for that process is started and is
then immutable for the duration of the process.
ewww... so no "fancy" capabilities like we could do in the old DOS days where
we could change the base environment as well as cloning it with changes for
child processes??? if so, that's blows several of my porting projects up :?
:(
Not possible on Posix platforms.
What you can do is execute the same binary again, but with the environment
variable added to the environment of the new process.
so, like the cloning process i mention above? that would have two copies of
the app in memory at once, right?
If you do an fpExec() without first a fpFork() you'll have only 1 copy in memory.
fpExec replaces the current process with a new process, and a new environment
can be specified for the new process.
