Parameters

[in]	zone	The zone of the packet where the counter can be found.
[in]	start_point	The start point for the checksum. Must be before the end_point.
[in]	start_offset	The offset from the specified start_point. Useful if the checksum does not include all of a 'zone'.
[in]	end_point	The end point for the checksum. Must be after the start_point.
[in]	end_offset	The offset from the specified end_point. Useful if the checksum does not include all of a 'zone'.
[in]	checksum_type	The type of checksum to be performed. The data type for the parameter must be compatible with the selected type.
[in]	polynomial	The polynomial to use for the CRC calculation. Typically written as 0x12345678. Only used if type is CT_GENERIC_CRC32.
[in]	init_value	The initial value to use for the CRC calculation. Typically 0 or 0xffffffff. Only used if type is CT_GENERIC_CRC32.
[in]	final_xor_value	The final value to perform the exclusive or on the checksum. Typically 0 or 0xffffffff. Only used if type is CT_GENERIC_CRC32.
[in]	reflect_input	Reflect the input (swap bit order). Only used if type is CT_GENERIC_CRC32.
[in]	reflect_result	Reflect the output (swap bit order). Only used if type is CT_GENERIC_CRC32.

Member Data Documentation

◆ checksum_type

The type of checksum to be performed.

The data type for the parameter must be compatible with the selected type.

◆ end_offset

The offset from the specified end_point.

Useful if the checksum does not include all of a 'zone'.

◆ end_point

The end point for the checksum.

Must be after the start_point.

◆ final_xor_value

The final value to perform the exclusive or on the checksum.

Typically 0 or 0xffffffff. Only used if type is CT_GENERIC_CRC32.

◆ init_value

The initial value to use for the CRC calculation.

Typically 0 or 0xffffffff. Only used if type is CT_GENERIC_CRC32.

◆ polynomial

The polynomial to use for the CRC calculation.

Typically written as 0x12345678. Only used if type is CT_GENERIC_CRC32.

◆ reflect_input

Reflect the input (swap bit order).

Only used if type is CT_GENERIC_CRC32.

◆ reflect_result

Reflect the output (swap bit order).

Only used if type is CT_GENERIC_CRC32.

◆ start_offset

The offset from the specified start_point.
