buffer_get_u16()

JAYLINK_PRIV uint16_t buffer_get_u16	(	const uint8_t *	buffer,
		size_t	offset
	)

Read a 16-bit unsigned integer value from a buffer.

The value in the buffer is expected to be stored in device byte order.

Parameters

[in]	buffer	Buffer to read the value from.
[in]	offset	Offset of the value within the buffer in bytes.

Returns

The value read from the buffer in host byte order.

buffer_get_u32()

JAYLINK_PRIV uint32_t buffer_get_u32	(	const uint8_t *	buffer,
		size_t	offset
	)

Read a 32-bit unsigned integer value from a buffer.

The value in the buffer is expected to be stored in device byte order.

Parameters

[in]	buffer	Buffer to read the value from.
[in]	offset	Offset of the value within the buffer in bytes.

Returns

The value read from the buffer in host byte order.

buffer_set_u16()

JAYLINK_PRIV void buffer_set_u16	(	uint8_t *	buffer,
		uint16_t	value,
		size_t	offset
	)

Write a 16-bit unsigned integer value to a buffer.

The value is stored in the buffer in device byte order.

Parameters

[out]	buffer	Buffer to write the value into.
[in]	value	Value to write into the buffer in host byte order.
[in]	offset	Offset of the value within the buffer in bytes.

buffer_set_u32()

JAYLINK_PRIV void buffer_set_u32	(	uint8_t *	buffer,
		uint32_t	value,
		size_t	offset
	)

Write a 32-bit unsigned integer value to a buffer.

The value is stored in the buffer in device byte order.

Parameters

[out]	buffer	Buffer to write the value into.
[in]	value	Value to write into the buffer in host byte order.
[in]	offset	Offset of the value within the buffer in bytes.
