## Member Function Documentation

void Gio::MemoryInputStream::add_data | ( | const void * | data,
|  | gssize | len,
|  | GDestroyNotify | destroy |
| ) |  |  |

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

Parameters:

  | data | Input data.
  | len | Length of the data, may be -1 if data is a null-terminated string.
  | destroy | A function to be called to free the data when it is no longer needed

Deprecated:
  Use version with destroy notification

void Gio::MemoryInputStream::add_data | ( | const void * | data,
|  | gssize | len |
| ) |  |  |

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

Note that the data will copied internally and freed when no longer needed.

Parameters:

  | data | Input data.
  | len | Length of the data, may be -1 if data is a null-terminated string.

void Gio::MemoryInputStream::add_data | ( | const std::string & | data | ) |

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

Parameters:

  | data | Input data.

const GMemoryInputStream* Gio::MemoryInputStream::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Provides access to the underlying C GObject.

Reimplemented from Gio::InputStream.

GMemoryInputStream* Gio::MemoryInputStream::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

## Friends And Related Function Documentation

Glib::RefPtr< Gio::MemoryInputStream > wrap | ( | GMemoryInputStream * | object,
|  | bool | take_copy = `false` |
| ) |  |  | `[related]`

A Glib::wrap() method for this object.

Parameters:

  | object | The C instance.
  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
