pmem2_source_get_handle() - reads file handler of the data source

       The pmem2_source_get_handle() function reads the file handler of *struct pmem2_source** object describing
       the data source and returns it by h parameter.

       This  function  is  Windows  only,  on Linux use pmem2_source_get_fd(3).  If the source was created using
       pmem2_source_from_fd(3) then pmem2_source_get_handle() is also valid function to  read  handler,  because
       file descriptor is converted to file handle during source creation.

       However,  there are limitations to what you can do with a handle created from a file descriptor.  For de‐
       tails refer to DESCRIPTION section in the pmem2_source_from_fd(3) manpage.

       The pmem2_source_get_handle() can fail with the following errors:

       • PMEM2_E_FILE_HANDLE_NOT_SET - in case of an instance of structpmem2_source that  does  not  come  from
         source type that support file handles, eg.  anonymous data source.

       The pmem2_source_get_handle() returns a file handle of data source.
