/* Interface for threads.
A module that plans to do a blocking system call (or something else that lasts a long time and doesn't touch Python data) can allow other threads to run as follows:
...preparations here... Py_BEGIN_ALLOW_THREADS ...blocking system call here... Py_END_ALLOW_THREADS ...interpret result here...
The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a {}-surrounded block. To leave the block in the middle (e.g., with return), you must insert a line containing Py_BLOCK_THREADS before the return, e.g.
if (...premature_exit...) { Py_BLOCK_THREADS PyErr_SetFromErrno(PyExc_IOError); return NULL; }
An alternative is:
Py_BLOCK_THREADS if (...premature_exit...) { PyErr_SetFromErrno(PyExc_IOError); return NULL; } Py_UNBLOCK_THREADS
For convenience, that the value of 'errno' is restored across Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND Py_END_ALLOW_THREADS!!!
The function PyEval_InitThreads() should be called only from initthread() in "threadmodule.c".
Note that not yet all candidates have been converted to use this mechanism! */
