See the "posix" module for example. Most functions are defined at interp-level, but there is also a file "app_posix.py" which just does "import posix" and happily calls interp-level code. > > > On Tue, Jun 9, 2015 at 9:30 AM, William ML Leslie < > william.leslie....@gmail.com> wrote: > >> On 8 June 2015 at 21:22, Yicong Huang <hengha....@gmail.com> wrote: >> >>> By reading modules in pypy/module, finally we found out the workaround >>> method. >>> >>> For most of modules in 'pypy/module', their interp code could not be >>> imported or used by other module's app code. >>> But there is special module '__pypy__', it exposed several interp >>> functions, and those code are used by other module's app code. >>> >> >> There's nothing special about __pypy__ for exposing interp-level code, >> the modules in pypy/modules usually include interp level code. >> >> For example, the select module exposes the interp-level function >> select_interp.select.
