The alternate function <<_putchar_r>> is a reentrant version. The extra argument <[reent]> is a pointer to a reentrancy structure. RETURNS If successful, <<putchar>> returns its argument <[ch]>. If an error intervenes, the result is <<EOF>>. You can use `<<ferror(stdin)>>' to query for errors. PORTABILITY ANSI C requires <<putchar>>; it suggests, but does not require, that <<putchar>> be implemented as a macro. Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>, <<lseek>>, <<read>>, <<sbrk>>, <<write>>. */ #if defined(LIBC_SCCS) && !defined(lint) static char sccsid[] = "%W% (Berkeley) %G%"; #endif /* LIBC_SCCS and not lint */ /* * A subroutine version of the macro putchar. */ #include <_ansi.h> #include <reent.h> #include <stdio.h> #include "local.h" #undef putchar int _DEFUN(_putchar_r, (ptr, c), struct _reent *ptr _AND int c) { _REENT_SMALL_CHECK_INIT (ptr); return _putc_r (ptr, c, _stdout_r (ptr)); } #ifndef _REENT_ONLY int _DEFUN(putchar, (c), int c) { _REENT_SMALL_CHECK_INIT (_REENT); return _putc_r (_REENT, c, _stdout_r (_REENT)); } #endif
