QuarkData* | get_qdata (GQuark quark) const |
This function gets back user data pointers stored via set_qdata(). More... | |
QuarkData* | steal_qdata (GQuark quark) |
This function gets back user data pointers stored via set_qdata() and removes the data from object without invoking its destroy() function (if any was set). More... | |

GstMemory is a lightweight refcounted object that wraps a region of memory.
They are typically used to manage the data of a #GstBuffer.
A GstMemory object has an allocated region of memory of maxsize. The maximum size does not change during the lifetime of the memory object. The memory also has an offset and size property that specifies the valid range of memory in the allocated region.
