Joe, Quincey,
Thanks for your answers.
I will try to see if we can get a "pseudo-null" value for each sensors
we are gathering data from.
Otherwise I can always define a dataset using a H5T_COMPOUND data type
as follow:
typedef struct s1_t
{
unsigned char emitted; // if 0 then no-val
float value;
} s1_t;
s1_tid = H5Tcreate(H5T_COMPOUND, sizeof(s1_t));
H5Tinsert(s1_tid, "emitted", HOFFSET(s1_t, emitted), H5T_NATIVE_UCHAR);
H5Tinsert(s1_tid, "value", HOFFSET(s1_t, value), H5T_NATIVE_FLOAT);
But this solution is more size consuming.
Best Regards,
Vincent
