Howdy HDF5 Folk!
I can't get a fill_value working for a string type - I don't know why.
I have the following code, it sets up a string variable with fill
value. But it does not work!
printf("*** Checking fill value...");
{
#define NUM_AMENDMENTS 27
#define NA 2
#define MAX_LEN 1024
#define GRP_NAME1 "Constitution"
#define VAR_NAME1 "Amendments"
char *data[NA];
char **data_in;
char amend[NA][MAX_LEN] = {"Congress shall make no law respecting an "
"establishment of religion, or prohibiting the
"
"free exercise thereof; or abridging the
freedom "
"of speech, or of the press; or the right of
the "
"people peaceably to assemble, and to petition
"
"the government for a redress of grievances.",
" A well regulated militia, being necessary to
the "
"security of a free state, the right of the
people "
"to keep and bear arms, shall not be
infringed."};
hsize_t dims_in[1], dims[1] = {NA};
hid_t fileid, grpid, spaceid, typeid, datasetid, plistid;
int i;
char fill_value[] = "";
char *f1 = fill_value;
for (i = 0; i < NA; i++)
data[i] = amend[i];
/* Open file. */
if ((fileid = H5Fcreate(FILE_NAME, H5F_ACC_TRUNC, H5P_DEFAULT,
H5P_DEFAULT)) < 0) ERR;
if ((grpid = H5Gcreate(fileid, GRP_NAME1, 0)) < 0) ERR;
/* Create string type. */
if ((typeid = H5Tcopy(H5T_C_S1)) < 0) ERR;
if (H5Tset_size(typeid, H5T_VARIABLE) < 0) ERR;
/* Write an dataset of this type. */
if ((spaceid = H5Screate_simple(1, dims, NULL)) < 0) ERR;
if ((plistid = H5Pcreate(H5P_DATASET_CREATE)) < 0) ERR;
if (H5Pset_fill_value(plistid, typeid, f1) < 0) ERR;
if ((datasetid = H5Dcreate(grpid, VAR_NAME1, typeid,
spaceid, plistid)) < 0) ERR;
if (H5Dwrite(datasetid, typeid, H5S_ALL, H5S_ALL, H5P_DEFAULT,
data) < 0) ERR;
When it gets to here I get an error from HDF5:
Program received signal SIGSEGV, Segmentation fault.
