	)

TESTPOINT: Statically define and initialize a memory slab

tmslab_alloc_align()

static void tmslab_alloc_align ( void *  data )

static

TESTPOINT: To ensure that each memory block is similarly aligned to this boundary

tmslab_alloc_free()

void tmslab_alloc_free

(

void *

data

)

TESTPOINT: The memory slab's buffer contains slab_num_blocks memory blocks that are slab_block_size bytes long.

TESTPOINT: Allocate memory from a memory slab.

TESTPOINT:

Return values

0	Memory allocated.

TESTPOINT: The block address area pointed at by mem is set to the starting address of the memory block.

TESTPOINT: Free memory allocated from a memory slab.

tmslab_alloc_timeout()

static void tmslab_alloc_timeout ( void *  data )

static

TESTPOINT: Use K_NO_WAIT to return without waiting

TESTPOINT: -ENOMEM Returned without waiting.

TESTPOINT: -EAGAIN Waiting period timed out

TESTPOINT: timeout Maximum time to wait for operation to complete (in milliseconds)

tmslab_used_get()

static void tmslab_used_get ( void *  data )

static

TESTPOINT: Get the number of used blocks in a memory slab.

TESTPOINT: Get the number of unused blocks in a memory slab.
