The netsnmp_iterator_info typedef can be used instead of directly calling this struct if you would prefer. .PP Definition at line 67 of file table_iterator.h. .SH "Field Documentation" .PP .SS "Netsnmp_Free_Data_Context* \fBnetsnmp_iterator_info_s::free_data_context\fP" .PP Frees a data context. This will be called at any time a data context needs to be freed. This may be at the same time as a correspondng loop context is freed, or much much later. Multiple data contexts may be kept in existence at any time.

This function is called at *each* iteration step, which is not-optimal for speed purposes. The use of free_loop_context_at_end instead is strongly encouraged. This can be set to NULL to avoid its usage.

Generally, this would free the loop context allocated by the get_first_data_point function (which would then be updated by each call to the get_next_data_point function). It is not called until the get_next_data_point function returns a NULL Definition at line 104 of file table_iterator.h. .PP Referenced by netsnmp_table_iterator_helper_handler(). .SS "Netsnmp_First_Data_Point* \fBnetsnmp_iterator_info_s::get_first_data_point\fP" .PP Responsible for: returning the first set of 'index' data, a loop-context pointer, and optionally a data context pointer.
