LockResource info  Overview  Group

The LockResource function locks the specified resource in memory.

LPVOID LockResource(

    HGLOBAL hResData 

// handle to resource to lock



Identifies the resource to be locked. The LoadResource function returns this handle.

Return Values

If the loaded resource is locked, the return value is a pointer to the first byte of the resource; otherwise, it is NULL.


It is not necessary for Win32-based applications to unlock resources that were locked by the LockResource function.

Trying to lock a resource by using the handle returned by the FindResource or FindResourceEx function will not work. You will get back a value that is incorrect and points to random data.
