### na_core_utils_dir_is_writable_uri ()

    gboolean            na_core_utils_dir_is_writable_uri   (const gchar *uri);

`uri` : | the URI of the directory to be tested.
Returns : | `TRUE` if the directory is writable, `FALSE` else. Please note that this type of test is subject to race conditions, as the directory may become unwritable after a successful test, but before the caller has been able to actually write into it. There is no "super-test". Just try...

                                                             const gchar *message);

Displays the permissions of the directory on debug output.

`path` : | the path of the directory to be tested.
`message` : | a message to be printed if not `NULL`.

### na_core_utils_dir_split_ext ()

    void                na_core_utils_dir_split_ext         (const gchar *string,
                                                             gchar **first,

Split the given `string`, returning the first part and the extension in newly allocated buffers which should be `g_free()` by the caller.

The extension is set to an empty string if no extension is detected.

`string` : | the input path or URI to be splitted.
`first` : | a pointer to a buffer which will contain the first part of the split.
`ext` : | a pointer to a buffer which will contain the extension part of the path.

### na_core_utils_file_delete ()

    gboolean            na_core_utils_file_delete           (const gchar *path);

`path` : | the path of the file to be deleted.
Returns : | `TRUE` if the file is successfully deleted, `FALSE` else.

Since 2.30

### na_core_utils_file_exists ()

    gboolean            na_core_utils_file_exists           (const gchar *uri);

`uri` : | a file URI.
Returns : | `TRUE` if the specified file exists, `FALSE` else. Race condition: cf. `na_core_utils_dir_is_writable_path()` and `na_core_utils_dir_is_writable_uri()` comments.

### na_core_utils_file_is_loadable ()

    gboolean            na_core_utils_file_is_loadable      (const gchar *uri);

Checks that the file is suitable to be loaded in memory, because it is not empty, and its size is reasonable (less than 1MB). Also checks that a file is a regular file (or a symlink to a regular file).

`uri` : | the URI to be checked.
Returns : | whether the file is suitable to be loaded in memory.

Since 3.1

### na_core_utils_file_load_from_uri ()

    gchar *             na_core_utils_file_load_from_uri    (const gchar *uri,
                                                             gsize *length);

Loads the file into a newly allocated buffer, and set up the length of the read content if not `NULL`.

`uri` : | the URI the file must be loaded from.
`length` : | a pointer to the length of the read content.
Returns : | the newly allocated buffer which contains the file content, or `NULL`. This buffer should be `g_free()` by the caller.
