Try the following.Perfo rm the following casting and see if it works.You should cast the farproc to char (__cdecl *)(void).
Hope it helps.
#include<stdio. h>
#include<window s.h>
int main(){
HANDLE ldll;
typedef char (*str)(void);
str Str;
ldll = LoadLibrary("my test.dll");
Str = (str)GetProcAdd ress(ldll, "str");

I think you should use the following format.
func(&temp)
and
void fun(char **temp)
int main()
{
char *temp = (char *)malloc(sizeof ("Hello" + 1));
strcpy(temp, "Hello");
fun(&temp);
printf("temp = %s\n", temp);
return 0;
}
void fun(char **temp)
{
*temp = (char *)malloc(sizeof ("World"...Leave a comment:

Doubt regarding extern usage
Will this compile? I have 1 header file , and it is included in 2 source files.
1. What about re-declaration error ? (for arraysize... )
2. #include always = textual substitution ??? Or does it have some intelligence ?
my header file - consts.h:
const int arraysize = 15;
my sources file 1 - op1.cpp:
#include "consts.h"
char array1[arraysize];
my source... -
it is to ensure that header file is included only onceLeave a comment:
