/* BEWARE:
|

|

Each interface exports both functions and macros. Extension modules

should normally use the functions for ensuring binary compatibility
|
||||
of the user's code across Python versions. Subsequently, if the
|
||||
Python runtime switches to its own malloc (different from standard
|
||||
malloc), no recompilation is required for the extensions.
|
||||
|
||||
The macro versions trade compatibility for speed. They can be used
|
||||
whenever there is a performance problem, but their use implies
|
||||
recompilation of the code for each new Python release. The Python
|
||||
core uses the macros because it *is* compiled on every upgrade.
|
||||
This might not be the case with 3rd party extensions in a custom
|
||||
setup (for example, a customer does not always have access to the

source of 3rd party deliverables). You have been warned! */

/* SCENARIOS
|
||||
|
||||
Here are two scenarios by Vladimir Marangozov (the author of the
|
||||
memory allocation redesign).
|
||||
|
||||
1) Scenario A
|
||||
|
||||
Suppose you want to use a debugging malloc library that collects info on
|
||||
where the malloc calls originate from. Assume the interface is:
|
||||
|
||||
d_malloc(size_t n, char* src_file, unsigned long src_line) c.s.
|
||||
|
||||
In this case, you would define (for example in config.h) :
|
||||
|
||||
#define PyCore_MALLOC_FUNC d_malloc
|
||||
...
|
||||
#define PyCore_MALLOC_PROTO (size_t, char *, unsigned long)
|
||||
...
|
||||
#define NEED_TO_DECLARE_MALLOC_AND_FRIEND
|
||||
|
||||
#define PyCore_MALLOC(n) PyCore_MALLOC_FUNC((n), __FILE__, __LINE__)
|
||||
...
|
||||
|
||||
2) Scenario B
|
||||
|
||||
Suppose you want to use malloc hooks (defined & initialized in a 3rd party
|
||||
malloc library) instead of malloc functions. In this case, you would
|
||||
define:
|
||||
|
||||
#define PyCore_MALLOC_FUNC (*malloc_hook)
|
||||
...
|
||||
#define NEED_TO_DECLARE_MALLOC_AND_FRIEND
|
||||
|
||||
and ignore the previous definitions about PyCore_MALLOC_FUNC, etc.
