Allocates a block of task memory in the same way that IMalloc::Alloc
| ULONG cb
||//Size in bytes of memory block to be allocated
Specifies the size (in bytes) of the memory block to be allocated.
Allocated memory block
Indicates memory block allocated successfully.
Indicates insufficient memory available.
function uses the default allocator to allocate a memory block in the same
way that IMalloc::Alloc
does. It is not necessary to call the CoGetMalloc
function before calling CoTaskMemAlloc
The initial contents of the returned memory block are undefined
there is no guarantee that the block has been initialized. The allocated block
may be larger than cb
bytes because of the space required for alignment and for maintenance
is zero, CoTaskMemAlloc
allocates a zero-length item and returns a valid pointer to that item. If
there is insufficient memory available, CoTaskMemAlloc
Applications should always check the return value from this method, even
when requesting small amounts of memory, because there is no guarantee the memory
will be allocated.
