Member Function Documentation

PSC_Hash_bytes()

uint64_t PSC_Hash_bytes	(	PSC_Hash *	self,
		const uint8_t *	data,
		size_t	size
	)

Calculate a hash from any data.

Parameters

self	the PSC_Hash
data	the data to hash
size	the size of the data

Returns

the hash value

PSC_Hash_create()

PSC_Hash * PSC_Hash_create	(	int	func,
		int	flags
	)

PSC_Hash default constructor.

Creates a new PSC_Hash with given options

Parameters

func	the hash function to use, currently ignored, only xxhash3 is available
flags	settings for the selected hash function, 0 means defaults. For xxhash3, 1 means use a random secret (created only once for all PSC_Hash instances) while hashing

Returns

a newly created PSC_Hash, or NULL on error

PSC_Hash_destroy()

void PSC_Hash_destroy

(

PSC_Hash *

self

)

PSC_Hash destructor.

Parameters

self	the PSC_Hash

PSC_Hash_string()

uint64_t PSC_Hash_string	(	PSC_Hash *	self,
		const char *	str
	)

Calculate a hash from a string.

Parameters

self	the PSC_Hash
str	the string to hash

Returns

the hash value
