NAME

SYNOPSIS
#include <stdio.h>
int puts(
const char *string);
PARAMETERS
string Points to a string to be written to output.
DESCRIPTION
The puts( ) function writes the null-terminated string pointed to by the string parameter, followed
by a newline character, to the standard output stream, stdout. This function does not write the
terminating null byte.
The st_ctime and st_mtime fields of the file are marked for update between the successful exe-
cution of the puts() function, and the next successful completion of a call to the fflush() or
fclose( ) function on the same stream, or a call to the exit() or abort() function.
RETURN VALUES
Upon successful completion, the puts() function returns the number of characters written. This
function can return EOF on an error.
ERRORS
The puts( ) function fails if either the standard output stream is unbuffered, or the stream’sbuffer
needed to be flushed and the function call caused an underlying write() or lseek() to be invoked
and this underlying operation fails with incomplete output. In addition, if any of the following
conditions occur, the puts() function sets errno to the corresponding value:
[EAGAIN] The O_NONBLOCK flag is set for the file descriptor of the underlying stream
and the process would be delayed in the write operation.
[EBADF] The file descriptor of the underlying stream is not a valid file descriptor open for
writing.
[EFBIG] An attempt was made to write to a file that exceeds the process’s file size limit or
the maximum file size.
[EINTR] The read operation was interrupted by a signal that was caught, and no data was
transferred.
[EIO] The implementation supports job control; the process is a member of a back-
ground process group attempting to write to its controlling terminal; TOSTOP is
set; the process is neither ignoring nor blocking SIGTTOU, and the process
group of the process is orphaned. This error might also be returned under
implementation-defined conditions.
