# IMalloc::GetSize

Returns the size (in bytes) of a memory block previously allocated with IMalloc::Alloc or IMalloc::Realloc.

ULONG GetSize(

void *pv | //Pointer to the memory block for which the size is requested
); |

Parameter

pv
  [in] Pointer to the memory block for which the size is requested.

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.
