9.4 Getting and Setting Parameter Information

The Global Call RTCM feature supports the retrieval or updating of multiple parameters of the same target object in a single Global Call API function call. The functions used to get and set configuration data are as follows:

gc_GetConfigData( )

retrieves the configuration data from a given target object

gc_SetConfigData( )

updates the configuration data of a given target object

The function call must include a valid target object that is consistent with the target ID. In addition, the following conditions must exist:

• Valid parameters (set ID and parm ID) supported by this target object
• Correct parameter data type and data value
• Appropriate control parameters (programming mode, timeout, update condition) have been set.

The set ID and parm ID as well as the data type and data value are specified in the function call using the GC_PARM_BLK data structure.
