This is part of Win16 API which allow to create versions of program from one source code to run under OS/2 and Win16. Under OS/2 program can be running under Win-OS/2 if program is Windows NE executable, and with help on Windows Libraries for OS/2, if it is OS/2 NE executable. Here is a WLO to OS/2 API mapping draft
LocalHeapSize
(Source: Windows KERNEL export list, ordinal 162)
Brief
Returns the size, in bytes, of the current local heap.
Syntax
WORD FAR PASCAL LocalHeapSize(void);
Parameters
This function has no parameters.
Return Value
Returns the total size, in bytes, of the current local heap. The “current” heap is the one whose data segment selector is loaded into the DS register at the time of the call.
Notes
The function operates on the local heap associated with the data segment currently addressed by the DS register. In normal use, called from within a module, it returns the total size of that module's own local heap. It can be used to determine the size of another program's local heap by temporarily loading its instance handle (selector) into DS, though this is rarely necessary in practice.
Example Code
C Binding
#include <windows.h> WORD wHeapSize = LocalHeapSize();
MASM Binding
call LocalHeapSize ; Returns AX = total size of current local heap
