|
Obtains the major and minor version numbers of the system that the specified DLL expects to run on. |
|
|
Obtains a handle to the heap of the calling process. |
|
|
Obtains information on the physical and virtual memory of the system. |
|
|
Allocates a block of memory from a heap. |
|
|
Compact a specified heap by combining adjacent free blocks of memory and decommitting large free blocks of memory. |
|
|
Creates a heap object that is private to the calling process. |
|
|
Destroys the specified heap object. |
|
|
Frees a memory block allocated from a heap by the HeapAllocor HeapReAllocfunction. |
|
|
Reallocates a block of memory from a heap. |
|
|
Returns the size, in bytes, of a memory block allocated from a heap by the HeapAllocor HeapReAllocfunction. |
|
|
Validates the specified heap. HeapValidatescans all the memory blocks in the heap and verifies that the heap control structures maintained by the heap manager are in a consistent state. The HeapValidatefunction can also be used to validate a single memory block within a specified heap without checking the validity of the entire heap. |
|
|
Checks whether the calling process has read access to the memory at the specified address. |
|
|
Checks whether the calling process has read access to the specified range of memory. |
|
|
Checks whether the calling process has write access to the specified range of memory. |
|

Allocates the specified number of bytes from the heap. |
|
|
Frees the specified local memory object and invalidates its handle. |
|
|
Changes the size or the attributes of a specified local memory object. |
|
|
Returns the current size, in bytes, of the specified local memory object. |
|
|
Fills a block of memory with zeros. |
|
|
Reserves or commits a region of pages in the virtual address space of the calling process. |
|
|
Releases or decommits, or both, a region of pages within the virtual address space of the calling process. |
|
|
This function changes the access protection on a region of committed pages in the virtual address space of the calling process. |
|
|
This function provides information about a range of pages in the virtual address space of the calling process. |
