Defined in File ziAPI.h
ZIResult_enum ziAPIEchoDevice(ZIConnection conn, const char *deviceSerial)#
Sends an echo command to a device and blocks until answer is received.
This is useful to flush all buffers between API and device to enforce that further code is only executed after the device executed a previous command. Per device echo is only implemented for HF2. For other device types it is a synonym to ziAPISync, and deviceSerial parameter is ignored.
conn – [in] Pointer to the ZIConnection that is to be synchronized
deviceSerial – [in] The serial of the device to get the echo from, e.g., dev2100
ZI_INFO_SUCCESS on success
ZI_ERROR_TIMEOUT when communication timed out
Other return codes may also be returned, for a detailed error message use ziAPIGetLastError.
