capture step an charcterised component cursor being shown windows

i wish constraint bitmap component cursor windows oses accurately possible.
the presumption api trust getcursorinfo, drawiconex.

the rudimentary method actions is:

• get cursor controlling getcursorinfo


• paint cursor memory dc controlling drawiconex.

here formula looks roughly.

cursorinfo  cursorinfo;

(void)memset(&cursorinfo, 0, sizeof(cursorinfo));
cursorinfo.cbsize = sizeof(cursorinfo);

if (getcursorinfo(&cursorinfo) &&
    cursorinfo.hcursor)
{
    // ... emanate here memory dc, memory bitmap

    boerror |= !drawiconex(hcursordc,   // device context
        0,              // xleft
        0,              // ytop
        cursorinfo.hcursor,     // cursor handle
        0,              // width, component default
        0,              // height, component default
        0,              // step charcterised cursor !!!!!!!!!
        null,               // nictitate giveaway brush, don't now
        di_mask | di_defaultsize);  // flags

    // ... whatever wish cursor the memory dc
}

now, anyone knows i step charcterised cursor being drawn (i need value following upheld istepifanicur parameter drawiconex...)? now above formula apparently always renders wholly initial step an charcterised cursor.

i think simply done, nonetheless it's value seeking anyway.
