DestroyIcon function (winuser.h)

Destroys an icon and frees any memory the icon occupied.

BOOL DestroyIcon(
  [in] HICON hIcon
);

[in] hIcon

Type: HICON

A handle to the icon to be destroyed. The icon must not be in use.

Type: BOOL

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

It is only necessary to call DestroyIcon for icons and cursors created with the following functions: CreateIconFromResourceEx (if called without the LR_SHARED flag), CreateIconIndirect, and CopyIcon. Do not use this function to destroy a shared icon. A shared icon is valid as long as the module from which it was loaded remains in memory. The following functions obtain a shared icon.

• LoadIcon
• LoadImage (if you use the LR_SHARED flag)
• CopyImage (if you use the LR_COPYRETURNORG flag and the hImage parameter is a shared icon)
• CreateIconFromResource
• CreateIconFromResourceEx (if you use the LR_SHARED flag)
