198 byte-stream mode, message-nondiscard mode, and message-discard mode.  The
199 default is byte-stream mode.  This can be changed using the \fBI_SRDOPT\fR
201 \fBioctl()\fR. In byte-stream mode, \fBread()\fR retrieves data from the stream
203 more data to be retrieved.  Byte-stream mode ignores message boundaries.
206 In streams message-nondiscard mode, \fBread()\fR retrieves data until as many

217 How \fBread()\fR handles zero-byte streams messages is determined by the
218 current read mode setting.  In byte-stream mode, \fBread()\fR accepts data
220 until a zero-byte message block is encountered. The \fBread()\fR function then
221 returns the number of bytes read, and places the zero-byte message back on the
223 \fBgetmsg\fR(2). In message-nondiscard mode or message-discard mode, a
224 zero-byte message returns \fB0\fR and the message is removed from the stream.
