Summary
Allocates a specified amount of memory and associates it with a safeguard.
Pascal
function GuardAllocMem(Size: Cardinal; out SafeGuard: ISafeGuard): Pointer;
Parameters
| Parameters | Description |
| Size: Cardinal | Size, in bytes, of the memory to allocate. This memory is allocated using the standard AllocMem function and as such is initialized to all zeros. |
| out SafeGuard: ISafeGuard | Receives a pointer to the ISafeGuard interface which is associated with the allocated memory. |
Return Value
Pointer to the block of allocated memory.
Description
GuardGetMem allocates the specified amount of memory and associates it with a safeguard. This function is identical to GuardGetMem except that the function uses AllocMem internally, as opposed to GetMem. As such the allocated memory is initialized with all zeros. A pointer to the allocated memory is returned as the function result. By using GuardGetMem you ensure that no matter how the scope in which the memory is allocated is left (e.g. by an exception or explicit Exit), the memory will be freed. See Guard for a more detailed description.
