PUTS(3C) Standard C Library Functions PUTS(3C)
NAME
puts, fputs - put a string on a stream
SYNOPSIS
#include <stdio.h>
int puts(
const char *s);
int fputs(
const char *s,
FILE *stream);
DESCRIPTION
The
puts() function writes the string pointed to by
s, followed by a
NEWLINE character, to the standard output stream
stdout (see
Intro(3)).
The terminating null byte is not written.
The
fputs() function writes the null-terminated string pointed to by
s to
the named output
stream. The terminating null byte is not written.
The
st_ctime and
st_mtime fields of the file will be marked for update
between the successful execution of
fputs() and the next successful
completion of a call to
fflush(3C) or
fclose(3C) on the same stream or a
call to
exit(2) or
abort(3C).
RETURN VALUES
On successful completion, both functions return the number of bytes
written; otherwise they return
EOF and set
errno to indicate the error.
ERRORS
Refer to
fputc(3C).
USAGE
Unlike
puts(), the
fputs() function does not write a NEWLINE character at
the end of the string.
