The active execution uses decay copies of the lvalue or rvalue references of fn and args, ignoring the value returned by fn. also see: call_once 函数 @microsoft std:call_once@cppreference.com 大意就是 call_one保证函数fn只被执行一次,如果有多个线程同时执行函数fn调用,则只有一个活动线程(...
This function template is defined in the C++ standard header <functional>. Pass instanceOfMyClass to getValue() using coder.ref to force the code generator to pass this variable by reference instead of by value. Get type callGetValue.m function out = callGetValue instanceOfMyClass = ...

1.For a static library, the actual code is extracted from the library by the linker and used to buildthe finalexecutable at the point you compile/build your application. 2.Each process gets its own copy of the code and data. Where as in case of dynamic libraries it is only code shared...
