6.2 Meta data printing

The EXTRACTOR_meta_data_print is a simple function which prints the meta data found with libextractor to a file. The function is mostly useful for debugging and as an example for how to manipulate the keyword list and can be passed as the ‘proc’ argument to EXTRACTOR_extract. The file to print to should be passed as ‘proc_cls’ (which must be of type FILE *), for example stdout.
