Virtual Method

GioFileEnumeratornext_file

Declaration [src]

GFileInfo*
next_file (
  GFileEnumerator* enumerator,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Returns information for the next file in the enumerated object. Will block until the information is available. The GFileInfo returned from this function will contain attributes that match the attribute string that was passed when the GFileEnumerator was created.

See the documentation of GFileEnumerator for information about the order of returned files.

On error, returns NULL and sets error to the error. If the enumerator is at the end, NULL will be returned and error will be unset.

Parameters

cancellable

Type: GCancellable

Optional GCancellable object, NULL to ignore.

The argument can be NULL.

The data is owned by the caller of the method.

error

Type: GError **

The return location for a recoverable error.

If the return location is not NULL, then you must initialize it to a NULL GError*.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

A GFileInfo or NULL on error or end of enumerator. Free the returned object with g_object_unref() when no longer needed.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.
