DELPI7编写的动态库，在PB中怎么声明
DELPI7编写的动态库，在PB中如何声明
DELPI7中 test.dll中的函数如下：
function gf_jmword(as_string: ShortString): wideString; stdcall;
functiongf_word(ac_word: pchar; ac_ts: integer): wideString; stdcall;
上边两个函数想在PB中调用，在PB中如何声明这连个函数，请各位指教。

外部函数就是用其他语言编写并储存在动态链接库里面的函数。这些动态链接库可以存放多个外部函数，外部函数可以是用VC++、Delphi等其他编程语言编写的。但是无论用什么语言编写，它都要符合基本的原则，就是必须用Pascal（16位）或标准（32位）调用规则编写，否则在PB中将无法调用。
PB中调用外部函数的语法是：
{access} FUNCTION returndatatype FunctionName ( { { REF} datatype1 arg1, …, {REF} datatypen argn}) LIBRARY “libname” ALLAS FOR “extname”
或：{access} SUBROUTINE SubroutineName ( { {REF} datatype1 arg1, … ,{REF} datatypen argn })
LIBRARY “libname” ALLAS FOR “extname”
由于编写语言的不同，所以肯定会有数据类型不匹配的问题，下表列出了C++和PB数据类型的转换对应关系：
C++数据类型 PB数据类型
Byte,Char Char
Bool Boolean
Char Blob
Char* String Ref
Double Double
Dword Ulong
Float Real
Handle Uint
Hwnd Ulong
Int Integer
Long Long
Lpbyte String Ref
Lpdword Ulong
Lpint Integer
Lplong Long
Lpstr String Ref
Lpviod String
Lpword Uint
Ulong/unsigned long Ulong
Unsigned int/Unsigned Short/Word Uint

拷贝一些调用方法,你参考:
FUNCTION ulong AbortDoc(ulong hdc) LIBRARY "gdi32.dll"
FUNCTION ulong AbortPath(ulong hdc) LIBRARY "gdi32.dll"
FUNCTION ulong AbortPrinter(ulong hPrinter) LIBRARY "winspool.drv"
FUNCTION ulong AbortSystemShutdown(ref string lpMachineName) LIBRARY "advapi32.dll" ALIAS FOR "AbortSystemShutdownA"
FUNCTION ulong AccessCheck(ref SECURITY_DESCRIPTOR pSecurityDescriptor,ulong ClientToken,ulong DesiredAccess,ref GENERIC_MAPPING GenericMapping,ref PRIVILEGE_SET PrivilegeSet,ref ulong PrivilegeSetLength,ref ulong GrantedAccess,ulong Status) LIBRARY "advapi32.dll"
