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