Description:
H5F_ACC_CREAT was included in the C++ API while the C library doesn't
allow it yet. Possibly, in the future, but not now. In addition, the
two flags H5F_ACC_RDONLY and H5F_ACC_RDWR were missing from the
documentation, causing confusion that appending is not supported.
Solution:
- Removed H5F_ACC_CREAT from the function until the C library support it
- Added H5F_ACC_RDONLY and H5F_ACC_RDWR to the comments to update the
documentation
Platforms tested:
Linux/ppc64 (ostrich)
Linux/32 2.6 (jam)
SunOS 5.11 (emu)

* January, 2005: C tests' macro VERIFY casts values to 'long' for all
|

|
||
* or int64 in VS C++ ostream, I casted the hssize_t values
|
