Function Documentation

seg* seg_new	(	long double	i_L,
		long double	i_d0,
		long double	i_d1
	)

creates new segment.

Parameters:

i_L	length of segment
i_d0	diameter at beginning of segment
i_d1	diameter at end of segment

Returns:

a new segment (free it with seg_free)

void seg_update

(

seg *

i_seg

)

updates private data of a segment.

Parameters:

i_seg

segment to be updated

seg* seg_copy

(

i_seg

)

copies a segment.

Parameters:

i_seg

segment to be copied

Returns:

a new segment (free it with seg_free)

void seg_free

(

seg *

i_seg

)

frees segment created with seg_new.

Parameters:

i_seg

segment to be freed

Eina_List* geo_new

(

)

creates new geometry structure.

Returns:

geometry (free it with geo_free)

void geo_free

(

Eina_List *
