 You can create your own sources and sinks by initializing the respective structures.

 For a source, only the `read_func` is mandatory, the other two functions are optional and used for initialization and cleanup, if required.
 The file source created by `cxPropertiesFileSource()`, for example,
 uses the `read_init_func` to allocate, and the `read_clean_func` to free the read buffer, respectively.

 Since the default map sink created by `cxPropertiesMapSink()` stores `char*` pointers into a map,
 the following example uses a different sink, which stores them as `cxmutstr` values, automatically freeing them
 when the map gets destroyed.
+And instead of reading the data from a file with `fread()`, it uses `mmap()` to map the file into memory for reading.
