Remote Procedure Calls (RPC)

19.3RPC Sample Code

Sample code for interfacing with the CMM through RPC is available in the file cli_client.c. The sample code compiles into a command-line executable for use with Linux or a .o file for use with VxWorks. To select the appropriate target, remove the comment from the appropriate #define in the source code.

The sample code first authenticates to the CMM through GetAuthCapability(). When the authentication is successful, the user’s command-line arguments (for Linux) or calling parameters (for VxWorks) are passed to the CMM through ChassisManagementApi(). The return code is then checked and the result is printed to the console.

19.4RPC Usage Examples

Table 85 presents examples of using RPC calls to get and set fields on the CMM. Data returned by RPC calls are returned in the ppvbuffer and uReturnType parameters to ChassisManagementApi().
