### <umalloc.h>

The <umalloc.h> include file defines the memory allocation functions that are heap-specific:

_debug_ucalloc | _ucalloc | _udump_allocated | _uheapset
_debug_uheapmin | _uclose | _udump_allocated_delta | _uheap_walk
_debug_umalloc | _ucreate | _uheapchk | _umalloc
_mheap | _udefault | _uheap_check | _ustats
_uaddmem | _udestroy | _uheapmin | _uopen

<umalloc.h> also defines macros used by the heap-specific functions.

Note: To use the debug versions of memory management functions, specify the debug memory (/Tm) compiler option.
