c++ - GetMenuItemInfo does not set fType with MIIM_TYPE -

i have been working winapi little bit, making project owner draw on menus. when called getmenuiteminfo, sets text of menu item, not ftype uint variable flags.
have declared:

menuitem->fmask = miim_type 

and msdn says:

miim_type retrieves or sets ftype , dwtypedata members. 

i don't know if got confused miim_type flag.

here code:

void setownerdrawmenu(hmenu * menu) { menuif * menu_item_information; hmenu sub_menu_ocational;  uint uid_menuitem; int nmenucountitems = getmenuitemcount(*menu);  menuiteminfo * menuitem = (menuiteminfo*)malloc(sizeof(menuiteminfo));  for(int i=0;i<nmenucountitems;i++) {      menu_item_information = (menuif*)malloc(sizeof(menuif));     menu_item_information->isseparator=false;     menu_item_information->max_width=0;     sub_menu_ocational = 0;     uid_menuitem = getmenuitemid(*menu,i);     memset(&menuitem,0,sizeof(menuitem));     menuitem = (menuiteminfo*)malloc(sizeof(menuiteminfo));     menuitem->cbsize = sizeof(menuitem);     menuitem->fmask = miim_type;     menuitem->cch = max_odm_cch;     menuitem->dwtypedata = menu_item_information->szitemtext;      getmenuiteminfo(*menu,uid_menuitem,false,menuitem);      uint final_flags = mf_byposition | mf_ownerdraw;      if( ( mft_separator & menuitem->ftype ) == mft_separator )     {         final_flags |= mf_separator;         menu_item_information->isseparator = true;     }     else     {         // not important stuff     }      sub_menu_ocational = getsubmenu(*menu,i);      if(sub_menu_ocational!=null)     {         modifymenu(*menu,i,final_flags,0,(lpctstr)menu_item_information);         // got submenu, repeat operation         setownerdrawmenu(&sub_menu_ocational);     }     else     {         modifymenu(*menu,i,final_flags,0,(lpctstr)menu_item_information);     } } } 

i inserting menus insertmenu function:

insertmenu(tid_cmenu,0,mf_byposition | mf_separator,0,null); insertmenu(tid_cmenu,0, mf_byposition | mf_string, tid_exit, "exit"); 

exactly, why getmenuiteminfo not retriving ftype?

if checking return code getmenuiteminfo see failing. error in line:

menuitem->cbsize = sizeof(menuitem);

the menuiteminfo::cbsize member supposed set size of menuiteminfo structure, setting size of menuiteminfo* pointer (i.e. 4 or 8 bytes, depending on platform).

change code to:

menuitem->cbsize = sizeof(menuiteminfo);

also, code allocating menuitem outside loop, once per-iteration inside loop, leaking memory.
