Routine Description:
|
||
|
|
||
|
This routine returns the maximum size of a buffer that starts at a given offset,
|
||
|
based on the size of the containing structure.
|
||
|
|
||
|
Arguments:
|
||
|
|
||
|
BaseAddress - The base address of the structure. The offset is computed relative to this.
|
||
|
|
||
|
OffsetInBytes - (BaseAddress + OffsetInBytes) points to the beginning of the buffer.
|
||
|
|
||
|
BaseStructureSizeInBytes - The size of the structure which contains the buffer.
|
||
|
|
||
|
Return Value:
|
||
|
|
||
|
max(BaseStructureSizeInBytes - OffsetInBytes, 0). If any operations wrap around,
|
||
|
the return value is 0.
