int8_t complete	(	parse_pgm_ctx_t	ctx[],
		const char *	buf,
		int16_t *	state,
		char *	dst,
		uint8_t	size
	)

complete() must be called with *state==0. It returns < 0 on error.

Else it returns: 2 on completion (one possible choice). In this case, the chars are appended in dst buffer. 1 if there is several possible choices. In this case, you must call the function again, keeping the value of state intact. 0 when the iteration is finished. The dst is not valid for this last call.

The returned dst buf ends with .

int8_t parse	(	parse_pgm_ctx_t	ctx[],
		const char *	buf
	)

Try to parse a buffer according to the specified context. The argument buf must ends with "\n\0". The function returns PARSE_AMBIGUOUS, PARSE_NOMATCH or PARSE_BAD_ARGS on error. Else it calls the associated function (defined in the context) and returns 0 (PARSE_SUCCESS).
