## Implemented Interfaces

GMemoryInputStream implements GSeekable and GPollableInputStream.

## Includes

    #include <gio/gio.h>

## Description

GMemoryInputStream is a class for using arbitrary memory chunks as input for GIO streaming input operations.

As of GLib 2.34, GMemoryInputStream implements GPollableInputStream.

## Functions

### g_memory_input_stream_new ()

    GInputStream *
    g_memory_input_stream_new (void);

Creates a new empty GMemoryInputStream.

#### Returns

a new GInputStream

### g_memory_input_stream_new_from_data ()

    GInputStream *
    g_memory_input_stream_new_from_data (const void *data,
                                         gssize len,
                                         GDestroyNotify destroy);

Creates a new GMemoryInputStream with data in memory of a given size.

#### Parameters

data | input data. | [array length=len][element-type guint8][transfer full]
len | length of the data, may be -1 if `data` is a nul-terminated string |
destroy | function that is called to free `data` , or `NULL`. | [allow-none]

#### Returns

new GInputStream read from `data` of `len` bytes.

### g_memory_input_stream_new_from_bytes ()

    GInputStream *
    g_memory_input_stream_new_from_bytes (GBytes *bytes);

Creates a new GMemoryInputStream with data from the given `bytes` .

#### Parameters

bytes | a GBytes |

#### Returns

new GInputStream read from `bytes`

Since: 2.34

### g_memory_input_stream_add_data ()

    void
    g_memory_input_stream_add_data (GMemoryInputStream *stream,
                                    const void *data,
                                    gssize len,
                                    GDestroyNotify destroy);

Appends `data` to data that can be read from the input stream

#### Parameters

stream | a GMemoryInputStream |
data | input data. | [array length=len][element-type guint8][transfer full]
len | length of the data, may be -1 if `data` is a nul-terminated string |
destroy | function that is called to free `data` , or `NULL`. | [allow-none]

### g_memory_input_stream_add_bytes ()

    void
    g_memory_input_stream_add_bytes (GMemoryInputStream *stream,
                                     GBytes *bytes);

Appends `bytes` to data that can be read from the input stream.

#### Parameters

stream | a GMemoryInputStream |
bytes | input data |

Since: 2.34

## Types and Values
