我在DLL中有一个函数(c头是):
int my_c_function(
const int cnames[10], const char *delim, size_t delim_size,
char *buffer, size_t *buffersize);
我试过
function my_c_function(cnames: Array of integer;
const delim : PAnsiChar;
delim_size : integer;
buffer : array of Byte;
BufferSize: integer): integer; cdecl;
implementation
function my_c_function(cnames: Array of integer;
const delim : PAnsiChar;
delim_size : integer;
buffer : array of Byte;
BufferSize: integer): integer; cdecl; external 'mydll.dll';
但是当我尝试调用该函数时它会崩溃。
但是下面的C#导入工作正常......
[DllImport("mydll.dll", CharSet = CharSet.Ansi,CallingConvention =CallingConvention.Cdecl)]
public static extern int my_c_function(int[] cnames, string delim, int delim_size, StringBuilder buffer, ref int BufferSize);
有什么想法吗?
我需要在Delphi中初始化Buffer和BufferSize吗?
答案 0 :(得分:3)
“Array of”是Delphi类型,与C数组或指针不兼容。试试这个,看它是否有效:
type
TIntArray10 = Array [0..9] of integer;
function my_c_function(cnames: TIntArray10;
const delim : PAnsiChar;
delim_size : cardinal;
buffer : PByte;
var BufferSize: cardinal): integer; cdecl;
