Appendix A: System Routines - Memory Management 861 HeapSize Declaration: DWORD HeapSize (HANDLE handle) Category(ies): Memory Management Description: Return the number of bytes allocated for the given heap block. Due to word alignment and minimum block size, this may not be the amount it was allocated with. Note that heap compression itself can in rare circumstances increase the size of a heap block by a couple of bytes; therefore it is best not to rely on HeapSize to determine the true size of a block of heap memory. Inputs: handle - Handle of a heap block allocated with one of the heap allocation routines. Outputs: Size of block of heap memory for handle. Assumptions: None Side Effects: None Availability: All versions of the TI-89 / TI-92 Plus. TI-89 / TI-92 Plus Differences: None See Also: HeapAlloc, HeapAllocThrow, HeapRealloc Example: HANDLE h1, h2; DWORD s1, s2; h1 = HeapAlloc( 4 ); s1 = HeapSize( h1 ); /* will be 8 since that is the minimum block size */ h2 = HeapAlloc( 11 ); s2 = HeapSize( h2 ); /* will be 12 since all blocks must be even in length */ TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
