Fields

magic: u32

VCOS_BLOCKPOOL_MAGIC

mutex: VCOS_MUTEX_T

Thread safety for Alloc, Free, Delete, Stats

align: VCOS_UNSIGNED

Alignment of block data pointers

flags: VCOS_UNSIGNED

Flags for future use e.g. cache options

block_data_size: usize

The size of the block data

block_size: usize

Block size inc overheads

name: *const c_char

Name for debugging

num_subpools: VCOS_UNSIGNED

num_extension_blocks: VCOS_UNSIGNED

Number of blocks in each dynamically allocated subpool

subpools: [VCOS_BLOCKPOOL_SUBPOOL_T; 8]

Array of subpools. Subpool zero is is not deleted until the pool is destroed. If the index of the pool is < num_subpools and subpool[index.mem] is null then the subpool entry is valid but "not currently allocated"
