do{$VAR1 = {'hv_store_ent' => {'text' => 'Stores C in a hash.  The hash key is specified as C.  The C
parameter is the precomputed hash value; if it is zero then Perl will
compute it.  The return value is the new hash entry so created.  It will be
NULL if the operation failed or if the value did not need to be actually
stored within the hash (as in the case of tied hashes).  Otherwise the
contents of the return value can be accessed using the C macros
described here.  Note that the caller is responsible for suitably
incrementing the reference count of C before the call, and
decrementing it if the function returned NULL.  Effectively a successful
hv_store_ent takes ownership of one reference to C.  This is
usually what you want; a newly created SV has a reference count of one, so
if all your code does is create SVs then store them in a hash, hv_store
will own the only reference to the new SV, and your code doesn\'t need to do
anything further to tidy up.  Note that hv_store_ent only reads the C;
unlike C it does not take ownership of it, so maintaining the correct
reference count on C is entirely the caller\'s responsibility.  hv_store
is not implemented as a call to hv_store_ent, and does not create a temporary
SV for the key, so if your key data is not already in SV form then use
hv_store in preference to hv_store_ent.

information on how to use this function on tied hashes.

it is assumed that the caller will raise a warning, and this function
will silently just set C to C<-1> and return zero.  If the

For case-insensitiveness, the "casefolding" of Unicode is used
instead of upper/lowercasing both the characters, see

perl_clone takes these flags as parameters:

without it we only clone the data and zero the stacks,

CLONEf_KEEP_PTR_TABLE
perl_clone keeps a ptr_table with the pointer of the old

this allows it to check if something has been cloned and not
clone it again but rather just use the value and increase the
refcount. If KEEP_PTR_TABLE is not set then perl_clone will kill
the ptr_table using the function

reason to keep it around is if you want to dup some of your own
variable who are outside the graph perl scans, example of this
code is in threads.xs create

CLONEf_CLONE_HOST
This is a win32 thing, it is ignored on unix, it tells perls
win32host code (which is c++) to clone itself, this is needed on
win32 if you want to run two threads at the same time,
if you just want to do some stuff in a separate perl interpreter

you don\'t need to do anything.

a successful hv_store takes ownership of one reference to C.  This is

hv_store_ent, and does not create a temporary SV for the key, so if your

If Configure detects this system has a signbit() that will work with
our NVs, then we just use it via the #define in perl.h.  Otherwise,
fall back on this implementation.  As a first pass, this gets everything
right except -0.0.  Alas, catching -0.0 is the main use for this function,
so this is not too helpful yet.  Still, at least we have the scaffolding
in place to support other systems, should that prove useful.


Configure notes:  This function is called \'Perl_signbit\' instead of a
plain \'signbit\' because it is easy to imagine a system having a signbit()
function or macro that doesn\'t happen to work with our particular choice
of NVs.  We shouldn\'t just re-#define signbit as Perl_signbit and expect
the standard system headers to be happy.  Also, this is a no-context
function (no pTHX_) because Perl_signbit() is usually re-#defined in
perl.h as a simple macro call to the system\'s signbit().
Users should just always call Perl_signbit().
