|
|
* 0 is the (silently ignored) invalid handle value; < 0 is an error code.

*
|
|
* this is 64 bits because we want tags to remain unique. (tags are a
|
|
* counter that disambiguate several subsequent uses of the same
|
|
* resource array slot). 32-bit handles aren't enough because the index
|

* field requires at least 12 bits, thus leaving only about 512K possible
|
