Clarify that _O_TEXT is ANSI.

This constant was originally added before such a distinction was made;
make it clear that _O_TEXT means ANSI text.

 The **`_open_osfhandle`** call transfers ownership of the Win32 file handle to the file descriptor. To close a file opened by using **`_open_osfhandle`**, call [`_close`](close.md). The underlying OS file handle is also closed by a call to **`_close`**. Don't call the Win32 function `CloseHandle` on the original handle. If the file descriptor is owned by a `FILE *` stream, then a call to [`fclose`](fclose-fcloseall.md) closes both the file descriptor and the underlying handle. In this case, don't call **`_close`** on the file descriptor or `CloseHandle` on the original handle.

 The **`_pipe`** function returns two file descriptors to the pipe in the *`pfds`* argument. The element *`pfds`*[0] contains the read descriptor, and the element *`pfds`*[1] contains the write descriptor. Pipe file descriptors are used in the same way as other file descriptors. (The low-level input and output functions **`_read`** and **`_write`** can read from and write to a pipe.) To detect the end-of-pipe condition, check for a **`_read`** request that returns 0 as the number of bytes read.
 
-The *`psize`* argument specifies the amount of memory, in bytes, to reserve for the pipe. The *`textmode`* argument specifies the translation mode for the pipe. The manifest constant `_O_TEXT` specifies a text translation, and the constant `_O_BINARY` specifies binary translation. (See [`fopen`, `_wfopen`](fopen-wfopen.md) for a description of text and binary modes.) If the *`textmode`* argument is 0, **`_pipe`** uses the default translation mode that's specified by the default-mode variable [`_fmode`](../fmode.md).

 ## Remarks
 
-The **`_setmode`** function sets to *`mode`* the translation mode of the file given by *`fd`*. Passing `_O_TEXT` as *`mode`* sets text (that is, translated) mode. Carriage return-line feed (CR-LF) combinations are translated into a single line feed character on input. Line feed characters are translated into CR-LF combinations on output. Passing `_O_BINARY` sets binary (untranslated) mode, in which these translations are suppressed.

 You can also pass `_O_U16TEXT`, `_O_U8TEXT`, or `_O_WTEXT` to enable Unicode mode, as demonstrated in the second example later in this document.
