Changes in v8: - In tep_record_print_selected_fields(), changing the argument 'ignore_mask' to 'select_maks'. - Fixes in the documentation of the new APIs. Changes in v7: - Proper naming (without 'tep' prefix) of the static methods defined in the patches. - Fixing the 'for' loop in print_selected_fields() - 'tep_print_selected_fields()' was renamed to 'tep_record_print_selected_fields()'. 'tep_record_print_fields()' was added. - Adding documentation for the new APIs. Changes in v6: - Cleanup in [PATCH 1/5]. - Protection against infinite loop in _tep_print_field() ([PATCH 4/5]). Changes in v5: - The loop over the tokens in _tep_print_field() is made circular in order to support the corner case when the fields and the tokens are listed in different order. - _tep_print_field() and print_selected_fields() are made "inline" in order to help the compiler to optimize out the unused variables (suggested by Steven). Changes in v4: - Directly applying the modification in tep_print_field() suggested by Steven. - Optimizing the loop over the tokens in tep_print_fields().
