## Name

mail::account::findFolder — A direct short-cut to a folder

## Synopsis

#include <libmail/mail.H>
class myCallback : public mail::callback {
public:
void success(std::string msg);
void fail(std::string msg);
};

class myFolderCallback : public mail::callback::folderlist {
public:
void success(const std::vector<const mail::folder *> &folders);
};

mail::account *account;
mail::folder *folder;
std::string folderPath=folder->getPath();

`mail::folder *folder=account->fsfuncfindFolder(` | std::string folderPath,
| myFolderCallback &folderCallback,
| myCallback &callback`)`;

## USAGE

This function is very similar to mail::account::folderFromString(3x). `mail::account::findFolder` recreates a mail::folder object, given its server path (which is returned by mail::folder::getPath(3x). The differences between `mail::account::findFolder` and `mail::account::folderFromString` are:

- `mail::account::folderFromString` uses a string created by `mail::account::folder::toString`, which includes all of the folder's properties (such as whether the folder contains messages, subfolders, or both, and its canonical name). `mail::account::findFolder` uses only the folder's "path", or "address" on the server.

### Note

The application must not destroy `folderCallback` until this request fails or succeeds. `folderCallback`'s `success` method is invoked just before the `callback`'s `success` method.

The `folderCallback.success` method receives a vector with a single pointer mail::folder object, that's initialized to represent the folder referenced by `folderPath`.

## RETURN CODES AND CALLBACKS

The application must wait until `callback`'s `success` or `fail` method is invoked. The `success` method is invoked when this request is succesfully processed. The `fail` method is invoked if this request cannot be processed. The application must not destroy `callback` until either the `success` or `fail` method is invoked.

### Note

`callback`'s `fail` method may be invoked even after other callback methods were invoked. This indicates that the request was partially completed before the error was encountered.

### Note

The `folderCallback.success` method receives a (possibly empty) vector of pointers to mail::folder objects. These objects will be destroyed when `folderCallback.success` terminates. The application must use mail::folder::clone(3x) to create copies of mail::folder objects it wants to use later.

### Note

Both `folderCallback.success` and `myCallback.success` method will be invoked if this request succeeds. `folderCallback.success` will be invoked before `myCallback.success` (since by definition this indicates that the request has been completed).

### Note

mail::folders are linked to their corresponding mail::accounts. A mail::folder created by one mail::account may not be used with a different mail::folder. All mail::folders created by a mail::account are invalidated when this mail::account object is destroyed. Note that the mail::folder objects are not automatically destroyed; the application is still responsible for destroying any remaining mail::folders, after their a mail::account is destroyed.
