Provides directory listing functions.

## Macros ##

### kSbDirectoryInvalid ###

Well-defined value for an invalid directory stream handle.

## Typedefs ##

### SbDirectory ###

A handle to an open directory stream.

#### Definition ####

```
typedef struct SbDirectoryPrivate* SbDirectory
```

## Structs ##

### SbDirectoryEntry ###

Represents a directory entry.

#### Members ####

*   `char name`

    The name of this directory entry.

## Functions ##

### SbDirectoryCanOpen ###

Indicates whether SbDirectoryOpen is allowed for the given `path`.

`path`: The path to be checked.

#### Declaration ####

```
bool SbDirectoryCanOpen(const char *path)
```

### SbDirectoryClose ###

Closes an open directory stream handle. The return value indicates whether the
directory was closed successfully.

`directory`: The directory stream handle to close.

#### Declaration ####

```
bool SbDirectoryClose(SbDirectory directory)
```

### SbDirectoryCreate ###

Creates the directory `path`, assuming the parent directory already exists. This
function returns `true` if the directory now exists (even if it existed before)
and returns `false` if the directory does not exist.

`path`: The path to be created.

#### Declaration ####

```
bool SbDirectoryCreate(const char *path)
```

### SbDirectoryGetNext ###

Populates `out_entry` with the next entry in the specified directory stream, and
moves the stream forward by one entry.

Platforms may, but are not required to, return `.` (referring to the directory
itself) and/or `..` (referring to the directory's parent directory) as entries
in the directory stream.

This function returns `true` if there was a next directory, and `false` at the
end of the directory stream.

`directory`: The directory stream from which to retrieve the next directory.
`out_entry`: The variable to be populated with the next directory entry.

#### Declaration ####

```
bool SbDirectoryGetNext(SbDirectory directory, SbDirectoryEntry *out_entry)
```

### SbDirectoryIsValid ###

Returns whether the given directory stream handle is valid.

#### Declaration ####

```
static bool SbDirectoryIsValid(SbDirectory directory)
```

### SbDirectoryOpen ###

Opens the given existing directory for listing. This function returns
kSbDirectoryInvalidHandle if it is not successful.

If `out_error` is provided by the caller, it will be set to the appropriate
SbFileError code on failure.

`out_error`: An output parameter that, in case of an error, is set to the reason
that the directory could not be opened.

#### Declaration ####

```
SbDirectory SbDirectoryOpen(const char *path, SbFileError *out_error)
```
