调用dll中函数的问题

[AI00]

函数在dll中声明void GetLpsz(LPSTR lpsz);
调用时
char lpsz[255];
fnGetLpsz( lpsz);//fnGetLpsz为取得的函数指针

最后运行时出现如下错误:
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

函数调用约定要一致

char lpsz[255];
LPSTR pp;
pp = lpsz;
fnGetLpsz( pp);

你的函数指针怎么定义的？

原函数：void GetLpsz(LPSTR lpsz);
函数指针： void (*pGetLpsz)(LPSTR);
