uint64_t LSM_DLL_EXPORT lsm_block_range_block_count_get ( lsm_block_range * br )

Retrieves the number of blocks to replicate.

Parameters:

br

Valid block range pointer

Returns:: value of number of blocks

uint64_t LSM_DLL_EXPORT lsm_block_range_dest_start_get ( lsm_block_range * br )

Retrieves the dest block address.

Parameters:

br

Valid block range pointer

Returns:: value of dest start.

lsm_block_range LSM_DLL_EXPORT* lsm_block_range_record_alloc	(	uint64_t	source_start,
		uint64_t	dest_start,
		uint64_t	block_count
	)

Creates memory for opaque data type to store a block range

Parameters:

	source_start	Source block number to replicate from
	dest_start	Dest block number to replicate to
	block_count	Number of blocks to replicate

Returns:: Valid block range ptr, otherwise NULL

Here is the caller graph for this function:

lsm_block_range LSM_DLL_EXPORT** lsm_block_range_record_array_alloc ( uint32_t size )

Allocates storage for an array of block ranges.

Parameters:

size

Number of elements to store.

Returns:: Pointer to memory for array of block ranges.

Here is the caller graph for this function:

int LSM_DLL_EXPORT lsm_block_range_record_array_free	(	lsm_block_range *	br[],
