Pointer error message with array type pointer

[Interner]

Hi

I keep on getting an error messge ''Pointer arithmetic involving null pointer''
The defnitions are:

long double time_rel_seq_ch[number_of_probes_active][max_nmb_blades*max_nmb_revs];

long double *p_time_rel_puls_1D_ch[number_of_probes_active]={(long double *)time_rel_puls_1D_ch[number_of_probes_active]};

Code is:

time_rel_seq_ch[number_of_probes][i]=*p_time_rel_puls_1D_ch[number_of_probes]++

I have tried everything and i dont have the knowledge to get past this one.

Thanks for your time

Unless the value of number_of_probes happens to be 0, you have not initialised p_time_rel_puls_1D_ch [number_of_probes], so it has a default value of 0 (under debug, or if declared static). You cannot perform operations (dereference, arithmetic etc) on uninitialised pointers - they must actually point to something first.
