Our sites are licensed to accept only household waste, apart from Thorn Turn Trade Waste Facility. The permit system prevents taxpayers footing the bill for commercial waste clean-ups. Remember to bring your permit with you when visiting the site. Alternatively, these can be posted to you but please allow 2 to 3 days for the permit to arrive. Permits will be emailed to you to either print at home or display on your smart device on arrival at the site. You no longer require a permit to dispose of fridges or freezers.
The HEAP_NO_SERIALIZE value can, therefore, be safely used only in the following situations:
Window tidy free free#
Without serialization, two or more threads that use the same heap handle might attempt to allocate or free memory simultaneously, likely causing corruption in the heap. Setting the HEAP_NO_SERIALIZE value eliminates mutual exclusion on the heap. There is a small performance cost to serialization, but it must be used whenever multiple threads allocate and free memory from the same heap. Serialization ensures mutual exclusion when two or more threads attempt to simultaneously allocate or free blocks from the same heap. Calling HeapFree twice with the same pointer can cause heap corruption, resulting in subsequent calls to HeapAlloc returning the same pointer twice. HeapSize) may not be used with freed memory, as they may return bogus data. Function calls that return information about memory (such as If you require information, do not free memory containing the information.
After that memory is freed, any information that may have been in it is gone forever. You should not refer in any way to memory that has been freed by GetLastError for extended error information. If the function fails, the return value is zero. If the function succeeds, the return value is nonzero. The system may create additional threads within the application's process, such as a CTRL+C handler, that simultaneously access the process heap.Ī pointer to the memory block to be freed. In this case, it is not necessary to additionally specify HEAP_NO_SERIALIZE in this function call.ĭo not specify this value when accessing the process heap. To ensure that serialized access is disabled for all calls to this function, specify HEAP_NO_SERIALIZE in the call to HeapCreate. Specifying the following value overrides the corresponding value specified in the flOptions parameter when the heap was created by using the Syntax BOOL HeapFree(Ī handle to the heap whose memory block is to be freed. Frees a memory block allocated from a heap by the
