带有指针结构的SWIG函数 [英] SWIG function with pointer struct
问题描述
我是使用SWIG封装C共享库的新手.
Im new using SWIG to wrapped C shared library.
我在用python中的Struct指针调用C函数时遇到问题.
I have problem to call a C function with Struct pointer in python.
我的文件:
ST_Param.h:
typedef struct {
unsigned int* device_Address;
....
....
unsigned int lock;
}ST_param_ST;
unsigned char ST_Param_Initialize(ST_param_ST * ST_param, unsigned int device_Address);
ST_Param.c
......... Rest of file.............
unsigned char ST_Param_Initialize(ST_param_ST * ST_param, unsigned int device_Address){
if(ST_param == NULL){
.......... rest of funtion .......................
return 0;
}
在ST_Param_Initialize内,如果不相信,我确认指针存在
Within ST_Param_Initialize I confirm that the pointer exists, if not believe
ST_Param.i :
/* File : ST_Param.i */
%module ST_Param
%{
#define SWIG_FILE_WITH_INIT
#include "ST_Param.h"
%}
%include "typemaps.i"
%include "ST_Param.h"
我编译并生成了一个.so文件. 在python中,我可以导入库,但由于需要ST_Param_ST *参数,因此无法调用ST_Param_Initialize:
I compiled and generated a .so file good. In python I can import a library but I cant call a ST_Param_Initialize because a need a ST_Param_ST * parameter:
我该怎么做?
注意:我无法修改.c和.h文件.只有.i文件.
Note: i cant modify a .c and .h file. Only a .i file.
在Google中进行搜索,但我不知道该怎么做
A search in google but I dont understand how to do it
谢谢 问候.
推荐答案
执行此操作的方式基本上与在C中执行此操作的方式相同:首先创建一个ST_param_ST
结构,然后将其传递给初始化函数ST_Param_Initialize()
.这是Python中的示例,假设您的模块名为ex
:
You do this essentially the same way you do it in C: You first create a ST_param_ST
struct and then pass this to the initialization function ST_Param_Initialize()
. Here is an example in Python, assuming your module is called ex
:
>>> import ex
>>> ST_Param = ex.ST_param_ST()
>>> ex.ST_Param_Initialize(ST_param, 42)
