IMalloc::GetSize method (objidlbase.h)
Retrieves the size of a previously allocated block of memory.
Syntax
SIZE_T GetSize(
[in] void *pv
);
Parameters
[in] pv
A pointer to the block of memory.
Return value
The size of the allocated memory block in bytes or, if pv is a NULL pointer, -1.
Remarks
To get the size in bytes of a memory block, the block must have been previously allocated with IMalloc::Alloc or IMalloc::Realloc. The size returned is the actual size of the allocation, which may be greater than the size requested when the allocation was made.
