FUNCTION
|
|
<<putchar_unlocked>>---non-thread-safe version of putchar (macro)
|
|
|
|
INDEX
|
|
putchar_unlocked
|
|
|
|
SYNOPSIS
|
|
#include <stdio.h>
|
|
int putchar_unlocked(int <[ch]>);
|
|
|
|
DESCRIPTION
|
|
<<putchar_unlocked>> is a non-thread-safe version of <<putchar>>
|
|
declared in <<stdio.h>>. <<putchar_unlocked>> may only safely be used
|
|
within a scope protected by flockfile() (or ftrylockfile()) and
|
|
funlockfile(). These functions may safely be used in a multi-threaded
|
|
program if and only if they are called while the invoking thread owns
|
|
the ( FILE *) object, as is the case after a successful call to the
|
|
flockfile() or ftrylockfile() functions. If threads are disabled,
|
|
then <<putchar_unlocked>> is equivalent to <<putchar>>.
|
|
|
|
RETURNS
|
|
See <<putchar>>.
|
|
|
|
PORTABILITY
|
|
POSIX 1003.1 requires <<putchar_unlocked>>. <<putchar_unlocked>> may
|
|
be implemented as a macro.
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>. */
