+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),
+or the interface may not be implemented on Linux.

+.SH NAME
+puts
+\(em put a string on standard output
+.SH SYNOPSIS
+.LP
+.nf
+#include <stdio.h>
+.P
+int puts(const char *\fIs\fP);
+.fi
+.SH DESCRIPTION
+The functionality described on this reference page is aligned with the
+ISO\ C standard. Any conflict between the requirements described here and the
+ISO\ C standard is unintentional. This volume of POSIX.1\(hy2008 defers to the ISO\ C standard.
+.P
+The
+\fIputs\fR()
+function shall write the string pointed to by
+.IR s ,
+followed by a
+<newline>,
+to the standard output stream
+.IR stdout .
+The terminating null byte shall not be written.
+.P
+The last data modification and last file status change timestamps
+of the file shall be marked for update between the successful
+execution of
+\fIputs\fR()
+and the next successful completion of a call to
+\fIfflush\fR()
+or
+\fIfclose\fR()
+on the same stream or a call to
+\fIexit\fR()
+or
+\fIabort\fR().
+.SH "RETURN VALUE"
+Upon successful completion,
+\fIputs\fR()
+shall return a non-negative number. Otherwise, it shall return EOF,
+shall set an error indicator for the stream,
+and
+.IR errno
+shall be set to indicate the error.
+.SH ERRORS
+Refer to
+.IR "\fIfputc\fR\^(\|)".
+.LP
+.IR "The following sections are informative."
+.SH EXAMPLES
+.SS "Printing to Standard Output"
+.P
+The following example gets the current time, converts it to a string
+using
+\fIlocaltime\fR()
+and
+\fIasctime\fR(),
+and prints it to standard output using
+\fIputs\fR().
+It then prints the number of minutes to an event for which it is
+waiting.

+.SH "APPLICATION USAGE"
+The
+\fIputs\fR()
+function appends a
+<newline>,
+while
+\fIfputs\fR()
+does not.
+.P
+This volume of POSIX.1\(hy2008 requires that successful completion simply return a non-negative
+integer. There are at least three known different implementation
+conventions for this requirement:
+.IP " *" 4
+Return a constant value.
+.IP " *" 4
+Return the last character written.
+.IP " *" 4
+Return the number of bytes written. Note that this implementation
+convention cannot be adhered to for strings longer than
+{INT_MAX}
+bytes as the value would not be representable in the return type of the
+function. For backwards compatibility, implementations can return the
+number of bytes for strings of up to
+{INT_MAX}
+bytes, and return
+{INT_MAX}
+for all longer strings.
+.SH RATIONALE
+None.
+.SH "FUTURE DIRECTIONS"
+None.
