### camel_message_info_load ()

    gboolean
    camel_message_info_load (CamelMessageInfo *mi,
                             const struct _CamelMIRecord *record,
                             gchar **bdata_ptr);

Load content of `mi` from the data stored in `record` . The `bdata_ptr` points to the current position of the record->bdata, where the read can continue. Use helper functions `camel_util_bdata_get_number()` and `camel_util_bdata_get_string()` to read data from it and also move forward the *bdata_ptr.

After successful load of the `mi` , the 'dirty' flag is unset.

#### Parameters

mi | a CamelMessageInfo to load |
record | a CamelMIRecord to load the `mi` from. | [type CamelMIRecord]
bdata_ptr | a backend specific data (bdata) pointer |

#### Returns

Whether the load was successful.

Since: 3.24

### camel_message_info_save ()

    gboolean
    camel_message_info_save (const CamelMessageInfo *mi,

[transfer full]

Since: 3.24

### camel_message_info_property_lock ()

    void
    camel_message_info_property_lock (const CamelMessageInfo *mi);

Acquires a property lock, which is used to ensure thread safety when properties are changing. Release the lock with `camel_message_info_property_unlock()`.

Note: Make sure the CamelFolderSummary lock is held before this lock, if there will be called any 'set' function on the `mi` , to avoid deadlock when the summary would be set as dirty while another thread might try to read values from the `mi` , waiting for the property lock and holding the summary lock at the same time.

#### Parameters

mi | a CamelMessageInfo |

Since: 3.24

### camel_message_info_property_unlock ()

    void
    camel_message_info_property_unlock (const CamelMessageInfo *mi);

#### Returns

Whether the `mi` is dirty, which means that it had been changed and a save to the local summary is required.

Since: 3.24

### camel_message_info_set_dirty ()

    void
    camel_message_info_set_dirty (CamelMessageInfo *mi,
                                  gboolean dirty);

Marks the `mi` as dirty, which means a save to the local summary is required.

#### Parameters

dirty | a dirty state to set |

Since: 3.24

### camel_message_info_get_folder_flagged ()

    gboolean
    camel_message_info_get_folder_flagged (const CamelMessageInfo *mi);

The folder flagged flag is used to mark the message infor as being changed and this change should be propagated to the remote store (server). This is different from the 'dirty' flag, which is set for local changes only. It can happen that the 'folder-flagged' flag is set, but the 'dirty' flag not.

This is only a convenient wrapper around CAMEL_MESSAGE_FOLDER_FLAGGED flag, for better readiness of the code.

#### Parameters

mi | a CamelMessageInfo |

#### Returns

Whether requires save of the local changes into the remote store.

Since: 3.24

The 'folder-flagged-stamp' is a stamp of the 'folder-flagged' flag. This stamp changes whenever anything would mark the `mi` as 'folder-flagged', regardless the `mi` being already 'folder-flagged'. It can be used to recognize changes on the 'folder-flagged' flag during the time.

#### Parameters

mi | a CamelMessageInfo |

#### Returns

Stamp of the 'folder-flagged' flag.

Since: 3.24

Change the state of the flags on the `mi` . Both `mask` and `set` are bit-or of CamelMessageFlags.

If the `mi` changed, the 'dirty' flag and the 'folder-flagged' flag are set automatically, unless the `mi` is aborting notifications. There is also emitted folder's "changed" signal for this `mi` , if necessary. In case the CAMEL_MESSAGE_FOLDER_FLAGGED flag would be set and the `mi` is not aborting notifications, the 'folder-flagged-stamp' changes too.

#### Parameters

If the `mi` changed, the 'dirty' flag and the 'folder-flagged' flag are set automatically, unless the `mi` is aborting notifications. There is also emitted folder's "changed" signal for this `mi` , if necessary.

#### Parameters

mi | a CamelMessageInfo |
name | user flag name |
state | state to set for the flag |

#### Returns

Whether the message info changed.

Since: 3.24
