Returns TRUE if any of the tests in the bitfield test areTRUE. For example, (G_FILE_TEST_EXISTS | G_FILE_TEST_IS_DIR)will return TRUE if the file exists; the check whether it’s a directory doesn’t matter since the existence test is TRUE. With the current set of available tests, there’s no point passing in more than one test at a time. |
| filename_display_basename |
Returns the display basename for the particular filename, guaranteed to be valid UTF-8. The display name might not be identical to the filename, for instance there might be problems converting it to UTF-8, and some files can be translated in the display. since: 2.6 |

Converts a filename into a valid UTF-8 string. The conversion is not necessarily reversible, so you should keep the original around and use the return value of this function only for display purposes.

Returns an allocated string with the absolute path name, or NULL if the program is not found in the path.
