SENDDATABYTES(3)

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 12. 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.
