How to avoid gcc warning in Python C extension when using Py_BEGIN_ALLOW_THREADS
问题 The simplest way to manipulate the GIL in Python C extensions is to use the macros provided: my_awesome_C_function() { blah; Py_BEGIN_ALLOW_THREADS // do stuff that doesn't need the GIL if (should_i_call_back) { Py_BLOCK_THREADS // do stuff that needs the GIL Py_UNBLOCK_THREADS } Py_END_ALLOW_THREADS return blah blah; } This works great, letting me release the GIL for the bulk of my code, but re-grabbing it for small bits of code that need it. The problem is when I compile this with gcc, I
