- GWEN_WAITCALLBACK:
- added text field to waitcallback
- added function/macro GWEN_WaitCallback_EnterWithText
- fixed GWEN_WaitCallback: If any previously activated callback returns
GWEN_WaitCallbackResult_Abort then all following callbacks will return
this code as well. Also the condition of returning this code is stored.
- introduced GWEN_WAITCALLBACK_ID_SIMPLE_PROGRESS
- introduced GWEN_WAITCALLBACK_ID_FAST
- introduced flags:
- defined flag GWEN_WAITCALLBACK_FLAGS_NO_REUSE
- defined depth level GWEN_WAITCALLBACK_LEVEL_REUSED
- replaced GWEN_BUFFEREDIO_CBID_IO with GWEN_WAITCALLBACK_ID_FAST
- replaced GWEN_NETCONNECTION_CBID_IO with GWEN_WAITCALLBACK_ID_FAST
- replaced GWEN_FSLOCK_CBID_IO with GWEN_WAITCALLBACK_ID_FAST
- README: Added listing of waitcallback ids
- added "LL" to GWEN_WAITCALLBACK_PROGRESS_NONE.
FIXME: We should better define a MAXVALUE, like GWEN_MAXVAL_UINT64 and
let configure determine this type (like the other stuff), because the
suffix "LL" tells the compiler that this is a "long long" value, which isn't
necessarily the case for 64 bit architectures...
