It must have been opened -for output. If no \fIchannelId\fR is specified then it defaults to -\fBstdout\fR. \fBPuts\fR normally outputs a newline character after -\fIstring\fR, but this feature may be suppressed by specifying the -\fB\-nonewline\fR switch. -.PP -Newline characters in the output are translated by \fBputs\fR to -platform-specific end-of-line sequences according to the current -value of the \fB\-translation\fR option for the channel (for example, -on PCs newlines are normally replaced with carriage-return-linefeed -sequences; on Macintoshes newlines are normally replaced with -carriage-returns). -See the \fBfconfigure\fR manual entry for a discussion on ways in -which \fBfconfigure\fR will alter output. -.PP -Tcl buffers output internally, so characters written with \fBputs\fR -may not appear immediately on the output file or device; Tcl will -normally delay output until the buffer is full or the channel is -closed. -You can force output to appear immediately with the \fBflush\fR -command. -.PP -When the output buffer fills up, the \fBputs\fR command will normally -block until all the buffered data has been accepted for output by the -operating system. -If \fIchannelId\fR is in nonblocking mode then the \fBputs\fR command -will not block even if the operating system cannot accept the data. -Instead, Tcl continues to buffer the data and writes it in the -background as fast as the underlying file or device can accept it. -The application must use the Tcl event loop for nonblocking output -to work; otherwise Tcl never finds out that the file or device is -ready for more output data. -It is possible for an arbitrarily large amount of data to be -buffered for a channel in nonblocking mode, which could consume a -large amount of memory. -To avoid wasting memory, nonblocking I/O should normally -be used in an event-driven fashion with the \fBfileevent\fR command -(don't invoke \fBputs\fR unless you have recently been notified -via a file event that the channel is ready for more output data). - -.SH "SEE ALSO" -fileevent(n) - -.SH KEYWORDS -channel, newline, output, write |
