Function Documentation

Printf_ConvertU16ToDecimal()

uint8_t Printf_ConvertU16ToDecimal	(	uint16_t	i,
		char	buffer[]
	)

Convert an unsigned 16-bit integer to its ASCII decimal representation.

Warning

The conversion is put in the buffer buffer in reverse order and without a final NUL character. The caller of this function then has to use the return value in order to use the characters in the buffer in the right order.

This function will always succeed.

Parameters

i	The 16-bit input value to convert.
buffer	A valid pointer to an allocated string of minimum size 5 bytes.

Returns

The number of characters actually written to the buffer.
