Hello Florian,
The flag H5F_ACC_CREAT is not supported in the main library and is removed from the C++ API in this coming release. The documentation will show the correct flags also, which are H5F_ACC_EXCL|H5F_ACC_TRUNC for creating new files and H5F_ACC_RDONLY?|H5F_ACC_RDWR for opening existing files Thanks, Binh-Minh ________________________________ From: Hdf-forum <[email protected]> on behalf of Florian Hoffmann <[email protected]> Sent: Wednesday, October 01, 2014 4:25 AM To: [email protected] Subject: [Hdf-forum] HDF5 1.8.9: H5F_ACC_CREAT Dear all, in the HDF5 version I am currently using (1.8.9) the flag H5F_ACC_CREAT is not working. An exception is thrown when I try to create a file like this: H5::H5File H5file_ptr = new H5File("./test.h5", H5F_ACC_CREAT); -> Exception at 0x761bc42d, code: 0xe06d7363: C++ exception, flags=0x1 (execution cannot be continued) (first chance) at c:\...\hdf5-1.8.9.tar\hdf5-1.8.9\hdf5-1.8.9\c++\src\h5file.cpp:121 refering to the following source code (h5file.cpp): void H5File::p_get_file(const char* name, unsigned int flags, const FileCreatPropList& create_plist, const FileAccPropList& access_plist) { // These bits only set for creation, so if any of them are set, // create the file. if( flags & (H5F_ACC_CREAT|H5F_ACC_EXCL|H5F_ACC_TRUNC|H5F_ACC_DEBUG)) { hid_t create_plist_id = create_plist.getId(); hid_t access_plist_id = access_plist.getId(); id = H5Fcreate( name, flags, create_plist_id, access_plist_id ); if( id < 0 ) // throw an exception when open/create fail { throw FileIException("H5File constructor", "H5Fcreate failed"); } } // Open the file if none of the bits above are set. else { hid_t access_plist_id = access_plist.getId(); id = H5Fopen( name, flags, access_plist_id ); if( id < 0 ) // throw an exception when open/create fail { throw FileIException("H5File constructor", "H5Fopen failed"); } } } A web search did not result in any information on if it has been solved or not in later releases. Does anyone have some information on this ? Furthermore, is my assumption correct, that this flag means: Create/Open file in Read/Write mode and keep file content if file already exists ?
