開發平台(Platform): (Ex: Win10, Linux, ...) 8051 編譯器(Ex: GCC, clang, VC++...)+目標環境(跟開發平台不同的話需列出) C51 問題(Question)：請問如何透過call by reference將struct中的pointer member傳給function 例如: typedef struct _AA { unsigned char Addr; unsigned char bIndex; unsigned char bLenAddrW; unsigned char *pDatAddrW; unsigned char bFlag; //bit0: Notify Busy //bit1: CmdByte Get //bit2: Address Write }_AAA; unsigned char Dat[10]; void func1(unsigned char*pLenAddrW, unsigned char**ppDatAddrW) { *pLenAddrW = aaa; *ppDatAddrW = Dat; } void main(void) { _AAA AAA; _AAA*pAAA = &AAA; func1(???, ???); //請問要怎麼透過pAAA將struct member的Address傳給func1?? } -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 36.226.177.132 ※ 文章網址: https://www.ptt.cc/bbs/C_and_CPP/M.1478944184.A.531.html ※ 編輯: MaxHaru (36.226.177.132), 11/12/2016 18:01:36
