That worked better for the bookTable_get_first_data_point method. Now I
am trying to use the my_loop_context in the
bookTable_get_next_data_point(void **my_loop_context,
void **my_data_context,
netsnmp_variable_list * put_index_data,
netsnmp_iterator_info *mydata)
{
char this_index[SPRINT_MAX_LEN];
//this printf shows the setting from the get_first_data_point method
printf("my_loop_context = %s\n",(char *)*my_loop_context);
snprintf(this_index, strlen((char *)*my_loop_context),
"%s",(const char*)*my_loop_context);
//this printf does not show the setting even though it should
printf("bookTable_get_next_data_point this index %s \n",this_index);
I don't seem to be able to access the data from my_loop_context in order
to increment to the next datapoint.

try
snmp_set_var_value( vptr, this_index, strlen(this_index));
The size of 'this_index' is SPRINT_MAX_LEN, but the index string doesn't
use all of this buffer. And 'this_index' is already a pointer to the
value, so you don't need to take the address again.
