(displayBuffer, errorBuffer, status) = RtlabApi.WaitExecutable (timeout)

• timeOut: Timeout in milliseconds to wait for results.

• fbElement: Functional block element which control is to be requested. This input is used to specify the acquisition groups or the subsystem id when the function block are OP_FB_ACQ_GROUP and OP_FB_SIGNAL respectively. Normally, this value is 0.

• priority: Control priority to be requested. Higher is the value, higher is the priority. See OP_CONTROL_PRIORITY.

• displayBuffer: Stdout outputs of the executable. When the executable wasn't started with OP_EXEC_FILE_OUTPUT_STDERR(2) option, this buffer also contains the stderr outputs.

• errorBuffer: Stderr output of the executable when the executable was started with the OP_EXEC_FILE_OUTPUT_STDERR(2). Otherwise, the string is empty.

• status: Status of the execution. True(1) when executable has finished, otherwise False(0).

• EOK: Success.

• OP_API_WAIT_EXEC_FILE: Error receiving results from the executable.
