LockResource

The LockResource function locks the specified resource in memory.

LPVOID LockResource(

HGLOBAL hResData	// handle to resource to lock
);

Parameters

hResData

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.

Remarks

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.
