| + | Returns the current size (in bytes) of a local memory object. | ||

| + | <code c>UINT WINAPI LocalSize( | ||
| + | HLOCAL hMem | ||
| + | );</ | ||
| - | ===== Syntax ===== | + | ==== Parameters |
| - | ===== Parameters ===== | + | hMem – Handle to the memory object. |
| - | ===== Return | + | ==== Return |
| - | ===== Notes ===== | + | Returns the size of the block, or zero if the handle is invalid or the object has been discarded. |
| - | ===== Example Code ===== | + | Call GetLastError for extended error information. |
| - | ==== C Binding | + | ==== Notes ==== |
| + | The returned size may be larger than the originally requested size because of internal alignment. | ||
| + | |||
| + | Use LocalFlags first to check whether the block has been discarded. | ||
