# SendDataBytes

## Name

SendDataBytes -- write data

## Synopsis

    #include <gpib/ib.h>

``void SendDataBytes`(int board_desc, const void *data, long count, int eot_mode);`

## Description

SendDataBytes() writes data to the bus. One or more devices must have already been addressed as listener (and the board as talker) before calling this function. Addressing may be accomplished with the SendSetup() function.

`count` bytes are written from the array specified by `data`. The `eot_mode` argument specifies how the message should be terminated, and may be any of the following values:

Table 1. eot modes

constant | value | description
--- | --- | ---
NULLend | 0 | Do not assert EOI or add a newline at the end of the write.
DABend | 1 | Assert EOI with the last byte of the write.
NLend | 2 | Append a newline, and assert EOI with the newline at the end of the write.

You may find it simpler to use the slightly higher level functions Send() or SendList(), since they does not require addressing and writing of data to be performed separately.
