Here is the caller graph for this function:

static int _curvePolySlide	(	sConstrain *	c,
		double	dist,
		void **	elm,
		sCoord *	p
	)			[static]

Dada uma curva (c) e o comprimento (dist) que se pretende projetar sobre a curva, a funcao calcula e retorna o ponto (p) correspondente ao comprimento projetado e a identificacao do segmento (elm) onde encontra-se o ponto. Caso o comprimento passado por parametro seja maior que o comprimento da curva a funcao retornara 0(zero).
