/* Signal handling:
This header file defines macros that allow your code to handle
interrupts received during processing. Interrupts that
could reasonably be handled:
SIGINT, SIGABRT, SIGALRM, SIGSEGV
****Warning***************
Do not allow code that creates temporary memory or increases reference
counts of Python objects to be interrupted unless you handle it
differently.
**************************
The mechanism for handling interrupts is conceptually simple:
- replace the signal handler with our own home-grown version
and store the old one.
- run the code to be interrupted -- if an interrupt occurs
the handler should basically just cause a return to the
calling function for finish work.
- restore the old signal handler
Of course, every code that allows interrupts must account for
returning via the interrupt and handle clean-up correctly. But,
even still, the simple paradigm is complicated by at least three
factors.
1) platform portability (i.e. Microsoft says not to use longjmp
to return from signal handling. They have a __try and __except
extension to C instead but what about mingw?).
2) how to handle threads: apparently whether signals are delivered to
every thread of the process or the "invoking" thread is platform
dependent. --- we don't handle threads for now.
3) do we need to worry about re-entrance. For now, assume the
code will not call-back into itself.
Ideas:
1) Start by implementing an approach that works on platforms that
can use setjmp and longjmp functionality and does nothing
on other platforms.
2) Ignore threads --- i.e. do not mix interrupt handling and threads
3) Add a default signal_handler function to the C-API but have the rest
use macros.
Simple Interface:
In your C-extension: around a block of code you want to be interruptable
with a SIGINT
NPY_SIGINT_ON
[code]
NPY_SIGINT_OFF
In order for this to work correctly, the
[code] block must not allocate any memory or alter the reference count of any
Python objects. In other words [code] must be interruptible so that continuation
after NPY_SIGINT_OFF will only be "missing some computations"
Interrupt handling does not work well with threads.

::
void
PyArray_ScalarAsCtype(PyObject *scalar, void *ctypeptr)
Convert to c-type
no error checking is performed -- ctypeptr must be same type as scalar
in case of flexible type, the data is not copied
into ctypeptr which is expected to be a pointer to pointer
::
int
PyArray_CastScalarToCtype(PyObject *scalar, void
*ctypeptr, PyArray_Descr *outcode)
Cast Scalar to c-type
The output buffer must be large-enough to receive the value

::
PyObject *
PyArray_FromAny(PyObject *op, PyArray_Descr *newtype, int
min_depth, int max_depth, int flags, PyObject
*context)
Does not check for ENSURECOPY and NOTSWAPPED in flags
Steals a reference to newtype --- which can be NULL
::
PyObject *
PyArray_EnsureArray(PyObject *op)
This is a quick wrapper around PyArray_FromAny(op, NULL, 0, 0, ENSUREARRAY)
that special cases Arrays and PyArray_Scalars up front
It *steals a reference* to the object
It also guarantees that the result is PyArray_Type
Because it decrefs op if any conversion needs to take place
so it can be used like PyArray_EnsureArray(some_function(...))
::
PyObject *
PyArray_EnsureAnyArray(PyObject *op)
::
PyObject *
PyArray_FromFile(FILE *fp, PyArray_Descr *dtype, intp num, char *sep)
Given a ``FILE *`` pointer ``fp``, and a ``PyArray_Descr``, return an
array corresponding to the data encoded in that file.
If the dtype is NULL, the default array type is used (double).
If non-null, the reference is stolen.
The number of elements to read is given as ``num``; if it is < 0, then
then as many as possible are read.
If ``sep`` is NULL or empty, then binary data is assumed, else
text data, with ``sep`` as the separator between elements. Whitespace in
the separator matches any length of whitespace in the text, and a match
for whitespace around the separator is added.
For memory-mapped files, use the buffer interface. No more data than
necessary is read by this routine.
::
PyObject *
PyArray_FromString(char *data, intp slen, PyArray_Descr *dtype, intp
num, char *sep)
Given a pointer to a string ``data``, a string length ``slen``, and
a ``PyArray_Descr``, return an array corresponding to the data
encoded in that string.
If the dtype is NULL, the default array type is used (double).
If non-null, the reference is stolen.
If ``slen`` is < 0, then the end of string is used for text data.
It is an error for ``slen`` to be < 0 for binary data (since embedded NULLs
would be the norm).
The number of elements to read is given as ``num``; if it is < 0, then
then as many as possible are read.
If ``sep`` is NULL or empty, then binary data is assumed, else
text data, with ``sep`` as the separator between elements. Whitespace in
the separator matches any length of whitespace in the text, and a match
for whitespace around the separator is added.
::
PyObject *
PyArray_FromBuffer(PyObject *buf, PyArray_Descr *type, intp
count, intp offset)
::
PyObject *
PyArray_FromIter(PyObject *obj, PyArray_Descr *dtype, intp count)
steals a reference to dtype (which cannot be NULL)
::
PyObject *
PyArray_Return(PyArrayObject *mp)
Return either an array or the appropriate Python object if the array
is 0d and matches a Python type.
::
PyObject *
PyArray_GetField(PyArrayObject *self, PyArray_Descr *typed, int
offset)
Get a subset of bytes from each element of the array
::
int
PyArray_SetField(PyArrayObject *self, PyArray_Descr *dtype, int
offset, PyObject *val)
Set a subset of bytes from each element of the array
::
PyObject *
PyArray_Byteswap(PyArrayObject *self, Bool inplace)
::
PyObject *
PyArray_Resize(PyArrayObject *self, PyArray_Dims *newshape, int
refcheck, NPY_ORDER fortran)
Resize (reallocate data). Only works if nothing else is referencing this
array and it is contiguous. If refcheck is 0, then the reference count is
not checked and assumed to be 1. You still must own this data and have no
weak-references and no base object.
::
int
PyArray_MoveInto(PyArrayObject *dest, PyArrayObject *src)
Move the memory of one array into another.
::
int
PyArray_CopyInto(PyArrayObject *dest, PyArrayObject *src)
Copy an Array into another array -- memory must not overlap.
::
int
PyArray_CopyAnyInto(PyArrayObject *dest, PyArrayObject *src)
Copy an Array into another array -- memory must not overlap
