使用libary分配和释放指针的内存 [英] hwo to allcoate and deallocate memory of pointer using libary

问题描述

动态库代码:

Dynamic lib code:

DYNAMICLIB_API int* aa1(void)
{
    int *a1;
    a1=(int*)malloc(sizeof(int));
    printf("Interger created\n");
    printf("bye");
    printf("good");
    printf("memory created");
     return a1;
}

我的主要功能代码:

my main function code:

int main(int argc, char* argv[])
{
    int *a1;
    a1=aa1();
    printf("Hello World!\n");
    free(a1);
    return 0;
}

代码产生运行时错误可以为您提供帮助.

推荐答案

您不应分配内存并将其释放到其他模块中，请参见 [

You shouldn''t allocate memory and release it in different modules, see "Allocating and freeing memory across module boundaries"[^].
The simpler solution is making your DLL exporting the ''release memory function''.
