Function Documentation

from_hex()

uint64_t from_hex	(	Str	str,
		size_t	max_len )

Converts a wire format string into a 64-bit integer.

Parameters

str	the wire format string to convert
max_len	the amount of characters to read from the string

Returns

a 64-bit integer with the value of the wire format

ImplList()

ImplList

(

HexByte

)

ListHexByte_print()

void ListHexByte_print	(	ListHexByte	list,
		char	end )

Print a list of hex bytes.

Parameters

list	the list of hex bytes to print
end	the character to end the print with

new_uuid()

UUID new_uuid

(

void

)

Creates a new UUID.

The UUID comes from /proc/sys/kernel/random/uuid

Returns

a new UUID

to_hex()

ListHexByte to_hex

(

uint64_t

n

)

Converts an entire 64-bit integer into the character representation.

Caller must free memory.

Parameters

n	the number to convert

Returns

the List of bytes the number represents

to_hex1()

HexByte to_hex1

(

unsigned char

c

)

Converts a single byte to the character representation.

Parameters

c	the byte to convert

Returns

a HexByte that represents that byte

UUID_deserialize()

UUID UUID_deserialize

(

Buffer

buf

)

Deserialize a Buffer into a UUID.

Parameters

buf	The Buffer you want to deserialize

Returns

The UUID that the Buffer represents

UUID_eq()

bool UUID_eq	(	UUID	lhs,
		UUID	rhs )

Compare 2 UUID's.

Parameters

lhs	the left-hand side of the equality
rhs	the right-hand side of the equality

Returns

whether the 2 UUID's ar equal or not

UUID_serialize()

Buffer UUID_serialize

(

UUID

uuid

)

Serialize a UUID into a Buffer.

Caller must free memory in Buffer.buf.

Parameters

uuid	the UUID you want to serialize

Returns

the Buffer that the UUID represents
