attribute((weak))的作用情况是这样的,碰到一个棘手的问题:我们不确定外部模块是否提供一个函数func,但是我们不得不用这个函数,即自己模块的代码必须用到func函数: extern int...所以这个时候,__attribute__((weak)) 派上了用场。...在自己的模块中定义: int __attribute__((weak)) func(...) { return ...
__attribute__((weak)) void FuncA(void) { printf("Weak FuncA!\r\n"); } /* 或者 *...

4、__attribute__((weak)): weak symbol,弱符号. 若存在两个相同的全局符号时,会引发重定义错误. 如果使用weak attribute,则当weak symbol和non-weak symbol同时存在的时候,linker会使用non-weak symbol.若只有weak symbol存在的时候则只使用weak symbol....
