GetAcqBlockLastVal

Group	Model Configuration, Acquisition
Description	Get the current settings for the blocking / non-blocking, and associated last value flag, for signal acquisition. This information is used by the API acquisition functions, which have the option not to wait for data, needed by some console's lack of multiple thread support. These settings apply to the current model. These settings only apply to the command station from which this call is made.
Required Control	None
Usage	(blockOnGroup, lastValues) = GetAcqBlockLastVal()
Input	None
Output	blockOnGroup: Acquisition group for which the API functions will wait for data (specify n for group n). If 0, API function will wait for data for all groups. If -1, API functions will not wait for any group's data. lastValues: Boolean, 1 means API functions will output the last values received while a group's data is not available. If 0, the API function will output zeroes. This parameter is ignored when blockOnGroup is not egal to -1.
Exception	EOK: success ENOMEM: memory allocation error EBADF: model not specified by previous OpalConnect or OpenProject EIO: error sending the request or receiving the reply from Controller
