Alisson, You can refer to the method's documentation here: http://www.gdal.org/ogr/classOGRGeometry.html#a674319670e735bf6d4049300096157ec
The mechanism of this operation was already explained Peter Halls in this mailing list[1]. GEOS does a good job identifying line strings touching at end points and then combining them to make rings and then polygons. However, it's your job to ensure that all the line strings passed to the method are part of a single polygon.
