Detailed Description

Specifies a custom allocation strategy.

Member Data Documentation

num_buffers_allocation_threshold

size_t num_buffers_allocation_threshold

Defines the minimum number of required free buffers.

If the number of free buffers falls below this, new buffers are allocated.

num_buffers_free_threshold

size_t num_buffers_free_threshold

Defines the maximum number of free buffers.

If the number of free buffers grows above this, buffers are freed.

If set to 0, buffers are not freed automatically.

Note

If num_buffers_free_threshold is not 0, it must be larger than num_buffers_allocation_threshold + 2.

num_buffers_max

size_t num_buffers_max

Defines the maximum total number of buffers this sink will allocate.

This includes both free buffers managed by the sink and filled buffers owned by the program.

If set to 0, there is no limit to the total number of buffers.
