求重量的函数为何参数不对

程序如下：
// CreateBlockExt.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "stdio.h"
#include <uf.h>
#include <uf_ui.h>
#include <uf_modl.h>
#include <uf_part.h>
#include "uf_weight.h"

#define UF_CALL(X) (report( __FILE__, __LINE__, #X, (X)))
static int report( char *file, int line, char *call, int irc)
{
 if (irc)
 {
 char messg[133];
 printf("%s, line %d: %s\n", file, line, call);
 (UF_get_fail_message(irc, messg)) ?
 printf(" returned a %d\n", irc) :
 printf(" returned error %d: %s\n", irc, messg);
 }
 return(irc);
}

static void do_ugopen_api(void)
{
int scope = 0;//只关闭当前文件，不涉及子装配
int mode = 1;//
char *edge_len[] = {"1.0","1.0","1.0"};//立方体各边长
double corner_pt[] = {0.0,0.0,0.0};//立方体原点坐标
tag_t block_tag;
tag_t part_tag;
/* 创建一个新的prt文件 */
UF_CALL(UF_PART_new("a_blank_part.prt",UF_PART_METRIC,&part_tag));
/* 在prt文件中创建一个立方体 */
UF_CALL(UF_MODL_create_block1(UF_NULLSIGN,corner_pt,edge_len,&block_tag));
UF_CALL(UF_MODL_set_body_density
(
block_tag,/*tag_t body, /* 
 solid/sheet body
 */
UF_MODL_kilograms_meters,/*UF_MODL_density_units_t units, /* 
 the unit of 'density'
 */
0.001/*double density /* 
 density of body
 */
));
UF_WEIGHT_units_type_t units=UF_WEIGHT_units_km;
UF_WEIGHT_properties_t properties;
char *cset_name;
char text[128];
cset_name=text;
UF_CALL(UF_WEIGHT_estab_solid_props(
 block_tag,/*const tag_t solid ,/* 
 The solid whose properties are to be
 calculated.
 */
 0.9,/*const double accuracy ,/* 
 The accuracy to which the solid's properties
 are to be calculated.
 */
 units,/*const UF_WEIGHT_units_type_t units ,/* 
 The units in which the properties are to be
 returned.
 */
 &properties/*UF_WEIGHT_properties_t * properties /* <O>
 The established properties of the solid.
 */
 ));
printf("%s",cset_name);
//UF_WEIGHT_sum_props()
/*保存此prt文件 */
UF_CALL(UF_PART_save());

/*关闭此prt文件 */
UF_CALL(UF_PART_close(part_tag,scope,mode));
}

int main(int argc, char* argv[])
{
if (!UF_CALL(UF_initialize()))
{
 do_UGopen_api();
 UF_CALL(UF_terminate());
}
return 0;
}

结果出错，错误信息是在UF_WEIGHT_estab_solid_props一句the first parameter passed in was invalid,第一个参数即block_tag,经逐句调试至少在运行这句前它是正确的指向那个正方体的，但为什么会出错呢？
