UG/OPEN API中的网格划分函数的参数类型如何知道？

UG/OPEN API中的函数UF_SF_create_2d_mesh和UF_SF_create_2d_ansys_mesh，他们的参数各有一个为结构体类型，  
函数原型定义分别如下：  
extern int UF_SF_create_2d_ansys_mesh (  
UF_SF_AMM_mesh_parameters_t * mesh_params,  
char * element_type,  
int num_objects,  
tag_t * object_id,  
tag_t * mesh_tag );  
和  
extern int UF_SF_create_2d_mesh (  
int num_objs,  
tag_t * objs_p,  
int num_hard_pnts,  
tag_t * hard_pnts_p,  
UF_SF_sfqm_mesh_data_t * mesh_data,  
tag_t * mesh_recipe );  
其中：  
UF_SF_AMM_mesh_parameters_t 和  
UF_SF_sfqm_mesh_data_t 的原型怎么查到？  
谢谢！

非常感谢tsingtsang 侠士，我的help里面没有，还有很多函数的参数都找不到，请问您是怎么找到的。有没有这方面的书籍？
向您鞠躬！

就是help里的东东，对应function的头文件里的结构体定义
  
书没有很合适的

谢谢tsingtsang ，我在help里面搜索，一直没有找到他的定义，在ugopen文件夹下的.h文件里。多谢了！

为什么，我用UF_SF_create_2d_mesh这个函数就是不能产生网格了？

为什么我用UF_SF_create_2d_mesh就是不能产生网格啊！
