大家好，今天要讲关于如何判断两个体是否干涉和获取系统日志的UFUN函数。

（1）UF_MODL_check_interference：这个函数的定义为根据单个目标体检查每个指定的工具体是否有干扰。

Defined in: uf_modl.h
 

Overview

Checks each specified tool body against the single target body for interference.
An interference status is returned for each tool body.

Objects may be created as part of the interference checking. These objects are
tagged for deletion, but to make sure the memory is freed and avoid memory overflow,
UF_MODL_update should be called following the call to UF_MODL_check_interference.

int UF_MODL_check_interference
(

tag_t target,
int num_tools,
tag_t * tools,
int * results

)

tag_t	target	Input	Target body against which interference is checked
int	num_tools	Input	Number of tool bodies specified in tools array
tag_t *	tools	Input	Tool bodies whose interference with target is inquired. Dimensioned to num_tools
int *	results	Output	Interference status for each tool body. The caller is responsible for allocating it with an array size of num_tools. = 1 -> there is interference = 2 -> no interference = 3 -> touching, that is coincident faces

第一个参数为目标体的Tag值

第二个参数为在工具数组中指定的工具体数目

第三个参数为与目标体干涉得到工具体

第四个参数为返回干涉状态

= 1 ->有干扰

= 2 ->无干扰

= 3 ->触碰，即重合面

（2）UF_ask_syslog_filename ：这个函数的定义为获取NX系统日志文件。

Defined in: uf.h
 

Overview

Get name of the current syslog

Output to UF_*free*

pointer to dynamically allocated path filename must be freed with UF_free()
