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>>. */ #if defined(LIBC_SCCS) && !defined(lint) static char sccsid[] = "%W% (Berkeley) %G%"; #endif /* LIBC_SCCS and not lint */ #include <_ansi.h> #include <reent.h> #include <stdio.h> #include <string.h> #include "fvwrite.h" #include "local.h" /* * Write the given string to stdout, appending a newline. */ int _DEFUN(_puts_r, (ptr, s), struct _reent *ptr _AND _CONST char * s) { size_t c = strlen (s); struct __suio uio; struct __siov iov[2]; iov[0].iov_base = s; iov[0].iov_len = c; iov[1].iov_base = "\n"; iov[1].iov_len = 1; uio.uio_resid = c + 1; uio.uio_iov = &iov[0]; uio.uio_iovcnt = 2; _REENT_SMALL_CHECK_INIT (ptr); ORIENT (stdout, -1); return (__sfvwrite_r (ptr, _stdout_r (ptr), &uio) ?
