Function Documentation

ethash_return_value_t ethash_full_compute	(	ethash_full_t	full,
		ethash_h256_t const	header_hash,
		uint64_t	nonce
	)

Calculate the full client data.

Parameters

full	The full client handler
header_hash	The header hash to pack into the mix
nonce	The nonce to pack into the mix

Returns: An object of ethash_return_value to hold the return value

Definition at line 575 of file internal.c.

Here is the caller graph for this function:

void const* ethash_full_dag ( ethash_full_t full )

Get a pointer to the full DAG data.

Definition at line 595 of file internal.c.

Here is the caller graph for this function:

uint64_t ethash_full_dag_size ( ethash_full_t full )

Get the size of the DAG data.

Definition at line 600 of file internal.c.

Here is the caller graph for this function:

void ethash_full_delete ( ethash_full_t full )

Frees a previously allocated ethash_full handler.

Parameters

full	The light handler to free

Definition at line 565 of file internal.c.

Here is the caller graph for this function:

ethash_full_t ethash_full_new	(	ethash_light_t	light,
		ethash_callback_t	callback
	)

Allocate and initialize a new ethash_full handler.

Parameters

light The light handler containing the cache.

callback A callback function with signature of ethash_callback_t It accepts an unsigned with which a progress of DAG calculation can be displayed. If all goes well the callback should return 0. If a non-zero value is returned then DAG generation will stop. Be advised. A progress value of 100 means that DAG creation is almost complete and that this function will soon return succesfully. It does not mean that the function has already had a succesfull return.

Returns: Newly allocated ethash_full handler or NULL in case of ERRNOMEM or invalid parameters used for ethash_compute_full_data()

Here is the call graph for this function:

Here is the caller graph for this function:

ethash_h256_t ethash_get_seedhash ( uint64_t block_number )

Calculate the seedhash for a given block number.

ethash_return_value_t ethash_light_compute	(	ethash_light_t	light,
		ethash_h256_t const	header_hash,
		uint64_t	nonce
	)

Calculate the light client data.

Parameters

light	The light client handler
header_hash	The header hash to pack into the mix
nonce	The nonce to pack into the mix

Returns: an object of ethash_return_value_t holding the return values
