Function Documentation

  int snmp_set_var_typed_value (netsnmp_variable_list * newvar, u_char type, const u_char * val_str, size_t val_len)

snmp_set_var_typed_value is used to set data into the netsnmp_variable_list structure. Used to return data to the snmp request via the netsnmp_request_info structure's requestvb pointer.

Parameters:
    newvar the structure gets populated with the given data, type, val_str, and val_len.
    type is the asn data type to be copied
    val_str is a buffer containing the value to be copied into the newvar structure.
    val_len the length of val_str

Returns:
    returns 0 on success and 1 on a malloc error

Examples:
delayed_instance.c.
