Function Documentation

net_field_length()

ulong STDCALL net_field_length

(

uchar **

packet

)

net_field_length_checked()

ulong STDCALL net_field_length_checked	(	uchar **	packet,
		ulong	max_length
	)

net_field_length_ll()

uint64_t net_field_length_ll

(

uchar **

packet

)

net_field_length_size()

uint net_field_length_size

(

const uchar *

pos

)

length of buffer required to represent a length-encoded string give the length part of length encoded string.

This function can be used before calling net_field_lenth/net_field_length_ll.

Parameters

[in]

pos

Length information of length-encoded string

Returns

length of buffer needed to store this number [1, 3, 4, 9].

net_length_size()

uint net_length_size

(

ulonglong

num

)

The length of space required to store the resulting length-encoded integer for the given number.

This function can be used at places where one needs to dynamically allocate the buffer for a given number to be stored as length- encoded integer.

Parameters

[in]

num

the input number

Returns

length of buffer needed to store this number [1, 3, 4, 9].

net_length_size_including_self()

uint64_t net_length_size_including_self

(

uint64_t

length

)

Calculates length of the field in case value of this field includes length of this field (self)

Parameters

length

Size of the field without self

Returns

Size of the field including self

net_store_length()

uchar * net_store_length	(	uchar *	packet,
		ulonglong	length
	)
