int PL_get_file_name(term_t spec, char **name, int flags)

Translate a Prolog term into a file name. The name is stored in the buffer stack described with the PL_get_chars() option BUF_STACK. Conversion from the internal UNICODE encoding is done using standard C library functions. flags is a bit-mask controlling the conversion process. Options are:

PL_FILE_ABSOLUTE: Return an absolute path to the requested file.
PL_FILE_OSPATH: Return the name using the hosting OS conventions. On MS-Windows, \ is used to separate directories rather than the canonical /.
PL_FILE_SEARCH: Invoke absolute_file_name/3. This implies rules from file_search_path/2 are used.
PL_FILE_EXIST: Demand the path to refer to an existing entity.
PL_FILE_READ: Demand read-access on the result.
PL_FILE_WRITE: Demand write-access on the result.
PL_FILE_EXECUTE: Demand execute-access on the result.
PL_FILE_NOERRORS: Do not raise any exceptions.
