GPIB 488.2 Porting Guide 986992 IOtech to Associated MCC APIs 3-11

RcvRespMsg is used to read data from a previously addressed device. You must address the

appropriate devices as Listeners/Talkers prior to calling this routine. The input data string is not

terminated with a zero byte.

In the following example, a previously addressed Listener receives 50 bytes of data from a

previously addressed Talker. The transmission is terminated when EOI is detected.

Example:

char data[50];

RcvRespMsg(0, data, 50, STOPend)

Receive is used to read data from a GPIB device. The input data string is not terminated with a

zero byte.

The following example instructs to receive 50 bytes of data from the specified talker (device at

address 2, connected to board). EOI signals the end of the message.

Example:

char data[50];

Receive (0, 2, data, 50, STOPend);
