Hello, I have been reading about STREAMS in various Unix Programming
books. I am working on Linux (RH 6), though. I found your site, and
installed the LiS package.
Right now, I am still a little overwhelmed by the incomplete examples in
the texts and documentation I have. I would like to just create a very
simple STREAMS example
program. I would like it to use the terminal device (pts/x), and then
call putmsg() which will send a message to the terminal.
I believe I need to define a string buffer as follows:
struct strbuf {
int maxlen; //max buffer length
int len; //length of data
char *buf //pointer to buffer
}
I would then initialize the string buffer with some data.
strbuf msg_buf;
char data[6] = "Hello\n";
msg_buf.maxlen = 1024;
msg_buf.len = 6;
msg_buf.buf = &data;
Then I would open a stream head with the open() function like follows:
fd = open("/dev/pts/0", O_RDWR);
Then I could call putmsg()
putmsg(fd, , msg_buf.buf, );
I am completely new to this, and I am sure I am missing much in my line
of thinking. Can anyone help out, or perhaps email me a simple piece of
code I can work with to accomplish this
task? Thanks in advance!
Davis
