|
|
int puts(const char *<[s]>);

TRAD_SYNOPSIS
|
||
|
|
#include <stdio.h>
|
||
|
|
int puts(<[s]>)
|
||
|
|
char *<[s]>;
|
||
|
|
|
||
|
|
int _puts_r(<[reent]>, <[s]>)

char *<[reent]>;
|
||
|
|
char *<[s]>;
|
||
|
|
|
||
|
|
DESCRIPTION
|
||
|
|
<<puts>> writes the string at <[s]> (followed by a newline, instead of
|
||
|
|
the trailing null) to the standard output stream.
|
||
|
|
|
||
|
|
The alternate function <<_puts_r>> is a reentrant version. The extra
|
||
|
|
argument <[reent]> is a pointer to a reentrancy structure.
|
||
|
|
|
||
|
|
RETURNS
|
||
|
|
If successful, the result is a nonnegative integer; otherwise, the
|
||
|
|
result is <<EOF>>.
|
||
|
|
|
||
|
|
PORTABILITY
|
||
|
|
ANSI C requires <<puts>>, but does not specify that the result on
|
||
|
|
success must be <<0>>; any non-negative value is permitted.
|
||
|
|
|
||
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
||
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>. */
