紧急求救acedSSGet的问题

buanhui

// Selects entities enclosed by the specified polygon.

pt3[X] = 10.0; pt3[Y] = 5.0; pt3[Z] = 0.0;

pt4[X] = 5.0; pt4[Y] = pt4[Z] = 0.0;

pointlist = acutBuildList(RTPOINT, pt1, RTPOINT, pt2,

         RTPOINT, pt3, RTPOINT, pt4, 0);

acedSSGet("WP", pointlist, NULL, NULL, ssname);
能否把pointlist 改造成根据Array的长度length()变化
例如当length()为4时，pointlist 就四个点
当length()为n时，pointlist 就n个点
