|
|
* It is somewhat common practice to use offsets aligned to their final

* type, and thus make sure you are not falling to this error in SourceMod.

|
|
* Specifying incorrect offsets or the incorrect data type for an offset
|
|
* can have fatal consequences. If you are hardcoding offsets, and the
|
|
* layout of CBaseEntity does not match, you can easily crash the server.
|
|
*
|
|
* The reasonable bounds for offsets is greater than or equal to 0 and
|
|
* below 32768. Offsets out of these bounds will throw an error. However,
|
|
* this does not represent any real range, it is simply a sanity check for
|
|
* illegal values. Any range outside of the CBaseEntity structure's private
|
|
* size will cause undefined behaviour or even crash.
