netsnmp_table_set_add_indexes() is used to define the structure of the
indexing foe the table as a whole. It takes a list of types - specifying
what sort of index is used for this table.
netsnmp_table_row_add_index() is used to specify the actual indexing
for a particular row of this table. It takes a list of *values* - which
should match the type(s) specified in netsnmp_table_set_add_indexes()
So you might have:
/* myTable1 */
netsnmp_table_set_add_indexes( table, ASN_INTEGER, /* End of
index list */ 0 );
netsnmp_table_row_add_index( row, ASN_INTEGER, /* Row # */ 4 );
Or
/* myTable2 */
netsnmp_table_set_add_indexes( table, ASN_OCTET_STR,
ASN_OCTET_STR, /* End of index list */ 0 );
netsnmp_table_row_add_index( row, ASN_OCTET_STR, /* first
index value */ "this" );
netsnmp_table_row_add_index( row, ASN_OCTET_STR, /* second
index value */ "that" );
The first table would include objects indexed using myTable1Column.4
The second table would include objects indexed using
myTable2Column."this"."that"
OK?
