ABI 编辑

General Details

This article describes the calling conventions with respect to js-ctypes while programming x86 and x86-64/x64/AMD64 architectures. A calling convention is an implementation-level (low-level) scheme regarding how subroutines receive parameters from their caller and how they revert.

ABI

ABI stands for  "Application Binary Interface".

Details with Respect to js-ctypes

This explains how to use it in the js-ctypes scope.

Three different ABIs exist: ctypes.default_abi, ctypes.stdcall_abi, and ctypes.winapi_abi.

ctypes.default_abi

Corresponds to cdecl; standard libraries use this ABI. You can also use this for various system calls,including those on Mac OS X and Linux.

ctypes.thiscall_abi

  More information is available at Bugzilla :: 552533.

ctypes.stdcall_abi

Used for calling functions declared with stdcall on Windows. These functions' names are automatically mangled for you by js-ctypes.

ctypes.winapi_abi

Used for calling Windows system functions. These are declared as stdcall on Windows, but do not have mangled names like those used by stdcall_abi above.

OS Specific

WIN32 and OS2

Callbacks in js-ctypes under these operating systems use a different ABI than regular function declarations.

Other

All other operating systems use ctypes.default_abi as their calling convention for all function declarations.
