LocalFree
The LocalFree function frees the specified local memory object and invalidates its handle.
HLOCAL LocalFree(
HLOCAL hMem
| // handle of local memory object
| );
|
|
Parameters
hMem
Identifies the local memory object. This handle is returned by either the LocalAlloc or LocalReAlloc function.
Return Values
If the function succeeds, the return value is NULL.
If the function fails, the return value is equal to the handle of the local
memory object. To get extended error information, call GetLastError.
Remarks
If the process tries to examine or modify the memory after it has been freed,
heap corruption may occur or an access violation exception
(EXCEPTION_ACCESS_VIOLATION) may be generated.
If the hMem parameter is NULL, LocalFree ignores the parameter and returns NULL.
LocalFree succeeds even if the memory object is locked by a previous call to the LocalLock function. The LocalLock function locks a local memory object and increments the lock count by one.
The LocalUnlock function unlocks it and decrements the lock count by one. To get the lock
count of a local memory object, use the LocalFlags function. LocalFree will free a locked memory object. A locked memory object has a lock count
greater than zero.
Both GlobalFree and LocalFree will free a locked memory object. However, if you run an application under a
debug version of Windows NT or Windows 95, both GlobalFree and LocalFree will issue a message that tells you that this is happening. If you are
debugging the application, GlobalFree and LocalFree will enter a hard-coded breakpoint just before freeing a locked object. This
lets you double-check the intended behavior.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
