SASSimpleSpaceToAddr
__C__ void * SASSimpleSpaceToAddr(SASSimpleSpace_t space)
Obtain the starting byte address of the simple space within the SASSimpleSpace_t block.
SASSimpleSpaceCreate
__C__ SASSimpleSpace_t SASSimpleSpaceCreate(block_size_t space_size)
Allocate a SAS block large enough to contain the requested SAS Simple Space.
SASSimpleSpaceDestroyNoLock
__C__ int SASSimpleSpaceDestroyNoLock(SASSimpleSpace_t space)
Destroy a SASSimpleSpace_t and free the shared storage block.
SASSimpleSpaceDestroy
__C__ int SASSimpleSpaceDestroy(SASSimpleSpace_t space)
Destroy a SASSimpleSpace_t and free the shared storage block.
SASSimpleSpaceInit
__C__ SASSimpleSpace_t SASSimpleSpaceInit(void *heap_block, block_size_t block_size, block_size_t space_size)
Initialize a shared storage block as a simple space.
SASSimpleSpaceFreeSpace
__C__ block_size_t SASSimpleSpaceFreeSpace(SASSimpleSpace_t space)
Return the block free space not occupied by control blocks and the simple space.
SASSimpleSpace_t
void * SASSimpleSpace_t
