Update
Description:
Changed includes of the form:
#include <hdf5_file.h>
to
#include "hdf5_file.h"
so that gcc can pick them up easier without including the system
header files since we don't care about them.
Platforms tested:
Linux

* April 14, 2000

*
|
|
* Purpose: Test HDF-SRB if it is configured and compiled. Read a chunk of
|
|
* dataset of an HDF5 file with an integer array on SRB server,
|
|
* using hyperslab.
|
|
* Usage: The HDF5 is built on the top of SRB. So you just need to
|
|
* activate a connection to SRB server by calling function
|
|
* H5Pset_fapl_srb()(after creating file property list by calling
|
|
* H5Pcreate()). All server information is passed in through its
|
|
* parameter SRB_Info(a structure). Its fields are
|
|
* char *srbHost: SRB host address of server. If the input is
|
|
* NULL, it will use the environment varible "srbHost" if
|
|
* it is defined. If it is not defined, the
|
|
* ~/.srb/.MdasEnd file will be checked next. If not, it
|
|
* will use the hostname of the client machine.
|
|
* char *srbPort: SRB host port number of server. If the
|
|
* input value is NULL, it will use the env variable
|
|
* "srbPort" if it is defined. If not, it defaults to
|
|
* 5558.
|
|
* char *srbAuth: SRB Authentication-password. It is used to
|
|
* define password for MDAS or SEA authentication.
|
|
* For SEA authentication, this is the password used by
|
|
* the SEA library to decrypt the encrypted private key
|
|
* stored in the file ~/.SEAuuuuu@ddddd(where uuuuu is
|
|
* the user ID and ddddd is the user domain name). This
|
|
* input is not needed if an unencrypted private key is
|
|
* available in the /tmp directory(generated using the
|
|
* 'seaauth auto' command). To provide additional
|
|
* flexibility, a client may also use the environment
|
|
* variable "srbAuth" to specify the password. A client
|
|
* may also supply the password in the ~/.srb/.MdasAuth
|
|
* file. If a client uses more than one method to specfy
|
|
* the password, the value given in this function call
|
|
* will take precedent, then the environment variable
|
|
* "srbAuth", and lastly, the ~/.srb/.MdasAuth file.
|
|
* int storSysType: Storage system type on SRB server.
|
|
* 0=Unix, 1=UniTree, 2=HPSS, 3=FTP, 4=HTTP
|
|
* int mode: File access mode, same definition with Unix.
|
|
* int size: File Size, only valid for HPSS, -1 is default
|
|
*
|
|
* Then you can open an HDF5 file by calling H5Fopen(). When
|
|
* you pass in the file name, it has to be file name with an
|
|
* absolute path. It you use SDSC server(ghidorah.sdsc.edu), your
|
|
* home directory is possibly in /projects/mdas/srb/SRBVault/.
