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).
