Declaration

gchar**
g_mount_guess_content_type_sync (
  GMount* mount,
  gboolean force_rescan,
  GCancellable* cancellable,
  GError** error
)

Description

Tries to guess the type of content stored on mount. Returns one or more textual identifiers of well-known content types (typically prefixed with “x-content/”), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info specification for more on x-content types.

This is a synchronous operation and as such may block doing IO; see g_mount_guess_content_type() for the asynchronous version.

Available since:2.18

Type: An array of utf8

A NULL-terminated array of content types or NULL on error. Caller should free this array with g_strfreev() when done with it.
