Detailed Description

The purpose of the default storage is three-fold:. 1) To create a global storage space without creating a whole bunch of globally accessible variables or a whole bunch of access functions to work with more privately restricted variables.

2) To provide a single location where the thread lock- ing needs to be implemented. At the time of this writing, however, thread locking is not yet in place.

3) To reduce the number of cross dependencies between code pieces that may or may not be linked together in the long run. This provides for a single loca- tion in which configuration data, for example, can be stored for a separate section of code that may not be linked in to the application in question.

The functions defined here implement these goals.

Currently, three data types are supported: booleans, inte- gers, and strings. Each of these data types have separate storage spaces. In addition, the storage space for each data type is divided further by the application level. Currently, there are two storage spaces. The first is reserved for the SNMP library itself. The second is intended for use in applications and is not modified or checked by the library, and, therefore, this is the space usable by you.

These definitions correspond with the 'storid' argument to the API

•   #define NETSNMP_DS_LIBRARY_ID 0

•   #define NETSNMP_DS_APPLICATION_ID 1

•   #define NETSNMP_DS_TOKEN_ID 2

These definitions correspond with the 'which' argument to the API, when the storeid argument is NETSNMP_DS_LIBRARY_ID

Function Documentation

  int netsnmp_ds_set_boolean (int storeid, int which, int value)

Stores 'true' or 'false' given an int value for value into netsnmp_ds_booleans[store][which] slot. Parameters:
    storeid an index to the boolean storage container's first index(store)
    which an index to the boolean storage container's second index(which)
    value if > 0, 'true' is set into the slot otherwise 'false'

Returns:
    Returns SNMPPERR_GENERR if the storeid and which parameters do not correspond to a valid slot, or SNMPERR_SUCCESS otherwise.
