Functions described here are available as a shared library, which can be compiled against and linked to with the libsystemdpkg-config(1) file. The code described here uses getenv(3), which is declared to be not multi-thread-safe. This means that the code calling the functions described here must not call setenv(3) from a parallel thread. It is recommended to only do calls to setenv() from an early phase of the program when no other threads have been started.

On success, this function returns a non-negative integer. On failure, it returns a negative errno-style error code.
