h5open
Open an HDF5 file
Calling Sequence
obj = h5open(filename [, access]) obj = h5open(filename, access, driver [, driver_options...])
Arguments
- filename
a string giving the filename
- access
A string giving the access mode to use
- driver
A string giving the driver name
- driver_options
A boolean or a double depending of the driver value
- obj
A H5Object corresponding to the open file
Description
Open an HDF5 file in using the access mode (by default "a").
The access mode is one of the five values:
- "r": read only, the file must exist.
- "r+": read/write, the file must exist.
- "w": create file, truncate if exists.
- "w-": create file, fail if exists.
- "a": read/write if exists, create otherwise (default).
Several drivers can be used:
- "sec2": Unbuffered, using standard POSIX functions.
- "stdio": Uses functions from the standard C stdio.h to perform I/O.
- "core": Uses a file in memory (improves read/write). This driver has two options:
- backingStore: a boolean, if %T (default), the changes are saved in the real file.
- blockSize: a double: increment (in bytes) to use to increase buffer size (default 64K).
- "family": Allow to split the file when its size is greater than the option memberSize (a double, by default 2^31 -1). The filename must contain a %d which will be used to generate the family filenames.
Examples
x = 1:10; save(TMPDIR + "/x.sod", "x"); // SOD files are HDF5 ones // Open the created file a = h5open(TMPDIR + "/x.sod"); // Dump the file content h5dump(a); // list the contents of the root element. h5ls(a) // Get the SOD version a.root.SCILAB_sod_version.data // or if the name contains 'invalid' chars a.root("SCILAB_sod_version").data // Get the content of the dataset x a.root.x.data // it is possible to open the dataset directly with its path // Subgroups or datasets are separated with '/' a("/x") // Free the resources h5close(a);
