* some possible errors are:
* \retval MDBX_EINVAL An invalid parameter was specified,
* or the environment has an active write transaction.
* \retval MDBX_EPERM Specific for Windows: Shrinking was disabled before
* and now it wanna be enabled, but there are reading
* threads that don't use the additional `SRWL` (that
* is required to avoid Windows issues).
* \retval MDBX_EPERM Two specific cases for Windows:
* 1) Shrinking was disabled before via geometry settings
* and now it enabled, but there are reading threads that
* don't use the additional `SRWL` (which is required to
* avoid Windows issues).
* 2) Temporary close memory mapped is required to change
* geometry, but there read transaction(s) is running
* and no corresponding thread(s) could be suspended
* since the \ref MDBX_NOTLS mode is used.
* \retval MDBX_EACCESS The environment opened in read-only.
* \retval MDBX_MAP_FULL Specified size smaller than the space already
* consumed by the environment.
