传入参数free_memory_start是内存初始化之后,剩余可申请的首地址,该地址,一般会传入到main函数,如果main()函数没有传入该参数的话,可以在内存初始化之后,自己malloc(4)申请一下,把返回的地址作为mm_management_init()函数的第一个参数; 传入参数free_memory_end是可以申请的最大地址,每个IC各有不同; mm_managemen...
注意多线程调试的话要决定是都让gdb锁定调度,另外如果要监视子进程,运行程序前还要设置set follow-fork-mode child属性。如果是自己编码实现调试的话,关系到内存地址的一些操作,建议启动程序前禁用掉Linux的地址空间随机化机制(ASLR,Address space layout randomization),避免麻烦(gdb自己会设置,不需要关注)。ASLR是防御...

set(CMAKE_SHARED_LIBRARY_PREFIX "") add_library(dll_poc SHARED main.c) 现在,两个上述文件都已修改,我们可以继续构建项目,这应该会在通用的cmake-debug-build目录中创建一个dll_poc.dll文件。 创建了dll_poc.dll文件后,我们可以通过使用rundll32快速测试DllMain函数是否正常工作而不出错。
