42 | DESCRIPTION |
||
43 | < |
||
44 | writes its argument to the standard output stream, |
||
45 | after converting it from an < |
||
46 | |||
47 | The alternate function <<_putchar_r>> is a reentrant version. The |
||
48 | extra argument <[reent]> is a pointer to a reentrancy structure. |
||
49 | |||
50 | RETURNS |
||
51 | If successful, < |
||
52 | intervenes, the result is < |
||
53 | query for errors. |
