I have been trying to write a template class for a shared memory
container, over the last few days - but I keep getting numerous compiler
errors e.g:
Error: syntax error : identifier 'myStaticShmemA llocator<void>'
Error: 'AllocationPoli cy' : undeclared identifier
Here is the truncated code below -
// template Header file
extern shared_memory static_shmem;
extern shared_memory dyn_shmem;
template <class T>
struct myStaticShmemAl locator
{
static T* Allocate(const size_t blocksize, const bool zeroed=true)
{
return static_shmem.al locate(blocksiz e, zeroed);
}
static void DeAllocate(T *ptr)
{
if(ptr);
static_shmem.fr ee(ptr) ;
}
};
template <class T>
struct myDynamicShmemA llocator
{
static T* Allocate(const size_t blocksize, const bool zeroed=true)
{
return dyn_shmem.alloc ate(blocksize, zeroed);
}
static void DeAllocate(T *ptr)
{
if(ptr);
dyn_shmem.free( ptr) ;
}
};
template <class ValueType, template <class SharedMemoryTyp eclass
AllocationPolic y= myStaticShmemAl locator<void
class myShmemHashTabl e
{
//Impl
};
//////// Code to test templates
struct MyStruct { int x; int y;};
int main(int argc, char* argv[])
{
//implicit creation in static shmem (using dflt tplt arg)
myShmemHashTabl e<MyStructa_sta tic ;
//explicit creation in static shmem
myShmemHashTabl e<MyStruct, myStaticShmemAl locator<void a1_static ;
//explicit creation in dynamic shmem
myShmemHashTabl e<MyStruct, myDynamicShmemA llocator<void a_dynamic;

Can't seem to get my head around the point of a trait class - no matter
how many times I read up on it - why not simply use functors or function
pointers ?
Anyone care to explain this in a simple straightforward way that a
simple guy from "Missourah" can understand ?

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
