DLL函数问题(100)

CI_SymEncrypt( long nFunction, unsigned char *pEntity, unsigned char *pPlainData, unsigned long nPlainLength, unsigned char *pCipherData, unsigned long *pnCipherLength);上面的函数是DLL中C语言的函数原型，转化成Delphi中，函数应该是什么样子啊？

function CI_SymEncrypt(nFunction:integer;pEntitychar;pPlainDatachar;nPlainLength:integer;pCipherDatachar;pnCipherLength:integer):integer;cdecl; external '*.dll';procedure CI_SymEncrypt(nFunction:integer;pEntitychar;pPlainDatachar;nPlainLength:integer;pCipherDatachar;pnCipherLength:integer);cdecl; external '*.dll';有return就用第一个，没有就用第二个；

接受答案了.
