| BOOL GlobalUnlock(hglb) | |||||
| HGLOBAL hglb; | /* handle of global memory to unlock | */ | |||
The GlobalUnlock function unlocks the given global memory object. This function has no effect on fixed memory.
hglb
Identifies the global memory object to be unlocked.
The return value is zero if the object's lock count was decremented (decreased by one) to zero. Otherwise, the return value is nonzero.
With movable or discardable memory, this function decrements the object's lock count. The object is completely unlocked and subject to moving or discarding if the lock count is decreased to zero.
This function returns nonzero if the given memory object is not movable. An application should not rely on the return value to determine the number of times it must subsequently call the GlobalUnlock function for the memory object.
Other functions can also affect the lock count of a memory object. For a list of the functions that affect the lock count, see the description of the GlobalFlags function.
Each time an application calls GlobalLock for an object, it must eventually call the GlobalUnlock function for the object.
