1、编译原理课程设计之函数调用分析（Compiler theory, curriculum design, function call analysis）There are 3 methods for calling functions in Windows systems: _stdcall, _cdecl, PASCALThe first two pass arguments from right to left, and the last is to pass arguments from left to right_stdcall is the standard way for Windo
2、ws systems to call API_cdecl is the standard invocation of ANSI-CThere are some differences between _stdcall and _cdecl:1._stdcall returns the EBP and ESP pointers from the called function, in this case f_stcall ()2._cdecl returns the EBP and ESP pointers by calling functions, in this case f_cdecl (
