SDL_GetEnvironment - Get the process environment.

       This function is available since SDL 3.2.0.

       This  is initialized at application start and is not affected by setenv() and unsetenv() calls after that
       point. Use SDL_SetEnvironmentVariable() and SDL_UnsetEnvironmentVariable() if you  want  to  modify  this
       environment,  or  SDL_setenv_unsafe()  or  SDL_unsetenv_unsafe()  if you want changes to persist in the C
       runtime environment after SDL_Quit().

       SDL_GetEnvironment - Get the process environment.

       Returns a pointer to the environment for the process or NULL on failure;  call  SDL_GetError()  for  more
       information.
