sint8 hexstr_2_bytes	(	uint8 *	pu8Out,
		uint8 *	pu8In,
		uint8	u8SizeOut
	)

Converts a string of hex characters to bytes.

Parameters

[out]	pu8Out	Output buffer (eg {0x11, 0x12, 0x13,...})
[in]	pu8In	Input buffer (eg {0x31, 0x31, 0x31, 0x32, 0x31, 0x33, ...})
[in]	u8SizeOut	Length of output buffer (should be half of the length of the input buffer).

Returns

M2M_SUCCESS if successful, M2M_ERR_INVALID_ARG otherwise (eg unrecognised hexchar in input).

uint8 m2m_checksum	(	uint8 *	buf,
		int	sz
	)

Calculates checksum for the specified number of data bytes in specified data buffer.

Parameters

[in]	sz	Number of data bytes used in the checksum calculation.
[in]	buf	The specified data buffer (whose data bytes will be used to calculate the checksum).

Returns

The calculated checksum.

sint8 m2m_memcmp	(	uint8 *	pu8Buff1,
		uint8 *	pu8Buff2,
		uint32	u32Size
	)

Compare specified number of data bytes in pu8Buff1 and pu8Buff2 and decide if they all match.

Parameters

[in]	pu8Buff1	One of two data buffers for the comparison.
[in]	pu8Buff2	One of two data buffers for the comparison.

Returns

Zero if matched, one if not matched.
