(That's clearly true, but not sure that's what XXX the text is trying to say.) PyArena_New() returns an arena pointer. On error, it returns a negative number and sets an exception. XXX (tim): Not true. On error, PyArena_New() actually returns NULL, XXX and looks like it may or may not set an exception (e.g., if the XXX internal PyList_New(0) returns NULL, PyArena_New() passes that on XXX and an exception is set; OTOH, if the internal XXX block_new(DEFAULT_BLOCK_SIZE) returns NULL, that's passed on but XXX an exception is not set in that case). */ PyAPI_FUNC(PyArena *) PyArena_New(void); PyAPI_FUNC(void) PyArena_Free(PyArena *); /* Mostly like malloc(), return the address of a block of memory spanning * `size` bytes, or return NULL (without setting an exception) if enough * new memory can't be obtained.
