Dear all,

this is the final version of the DRMAAv2 C binding. Please check if your favorite last change was correctly incorporated. The document will go to the OGF editors in 24 hours.

Best regards,

> - Roger, Peter: "principle of least astonishment, no NULLing in the library"
> - Andre, Daniel, Mariusz: "security problem, asynchronous free problem, OpenMPI example"
> - 3:2 voting result for changing the API -> free* functions get pointer variable reference and assign NULL to it
> - Voting also clarified that no other API changes are made
> 
>>  - Problems with OStype and CPUtype enumerations
> 
> - No decision at OGF35, voting needed
> - 5:0 voting result for keeping MACOS identifier - OS version is already a separate concept in the API
> - 5:0 voting result for changing TRUE64 to TRU64
> - 5:0 voting result for adding 64bit variations of all instruction set architectures
> - These changes demand an errata for the DRMAAv2 root specification
>

> 
> - No decision at OGF35, voting needed
> - 5:0 voting result for the proposal by Rayson Ho: DATA_SEG_SIZE is renamed to DATA_SIZE

>>  - Additional free functions needed

> - Native drmaa2_string type, instead of char* pointers
>     - OGF35 decision acknowledged by Roger
> - UNSET for JobInfo: 5:0 voting for adding it
