Memory, Cache, and Agent Key Management

The following functions free memory allocated by the Policy Management API:

• Sm_PolicyApi_FreeMemory() and Sm_PolicyApi_FreeMemoryEx() free any of the linked list pointers that are returned by the API.
• Sm_AgentApi_FreeServers() frees an array of server structures allocated by Sm_AgentApi_GetConfig(). Sm_PolicyApi_FreeStringArray() frees arrays of returned strings.

Another management command, Sm_PolicyApi_ManagementCommand(), performs cache and agent encryption key management, such as:

• Flushing all caches
• Flushing users cache
• Flushing realms from the resource cache
• Changing dynamic keys
• Changing persistent keys

The type of management operation you want to perform is determined by the management command you pass to Sm_PolicyApi_ManagementCommand().
