Glib::RefPtr<Gst::Memory> Gst::Allocator::alloc | ( | gsize | size, |
AllocationParams | params | ||
) |
Use allocator to allocate a new memory block with memory that is at least size big.
The optional params can specify the prefix and padding for the memory. If 0
is passed, no flags, no extra prefix/padding and a default alignment is used.
The prefix/padding will be filled with 0 if flags contains Gst::MEMORY_FLAG_ZERO_PREFIXED and Gst::MEMORY_FLAG_ZERO_PADDED respectively.
When allocator is 0
, the default allocator will be used.
The alignment in params is given as a bitmask so that align + 1 equals the amount of bytes to align to. For example, to align to 8 bytes, use an alignment of 7.
