Me again,
I've noticed that h5dump seems to truncate comments. On 1.8.5-patch1
the code like
char buf[] =
"abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
// Write comment to new file
const hid_t f = H5Fcreate(
"foo.h5", H5F_ACC_TRUNC, H5P_DEFAULT, H5P_DEFAULT);
hsize_t dims = 1;
int dat = 5;
H5LTmake_dataset_int(f, "x", 1, &dims, &dat);
H5Oset_comment_by_name(f, "x", buf, H5P_DEFAULT);
H5Fclose(f);
// Clear buf
memset(buf, 0, sizeof(buf));
puts(buf);
// Re-open file read-only and read comment
const hid_t g = H5Fopen("foo.h5", H5F_ACC_RDONLY, H5P_DEFAULT);
H5Oget_comment_by_name(g, "x", buf, sizeof(buf), H5P_DEFAULT);
puts(buf);
H5Fclose(g);
generates a foo.h5 file for which h5dump shows
HDF5 "foo.h5" {
GROUP "/" {
DATASET "x" {
COMMENT "abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMN"
DATATYPE H5T_STD_I32LE
DATASPACE SIMPLE { ( 1 ) / ( 1 ) }
DATA {
(0): 5
}
}
}
}
where the comment looks truncated. The H5Oget_comment_by_name in the
program, however, confirms that the full comment is being set.
Is there a way to request that h5dump not truncate comments?
Thanks,
Rhys
