DESCRIPTION |
|
|
73 |
The <> function or macro is the wide-character equivalent of |
|
|
74 |
the <> function. It writes the wide character wc to stdout. |
|
|
75 |
|
|
|
76 |
<> is a non-thread-safe version of <>. |
|
|
77 |
<> may only safely be used within a scope |
|
|
78 |
protected by flockfile() (or ftrylockfile()) and funlockfile(). This |
|
|
79 |
function may safely be used in a multi-threaded program if and only |
|
|
80 |
if they are called while the invoking thread owns the (FILE *) |
|
|
81 |
object, as is the case after a successful call to the flockfile() or |
|
|
82 |
ftrylockfile() functions. If threads are disabled, then |
|
|
83 |
<> is equivalent to <>. |
|
|
84 |
|
|
|
85 |
The alternate functions <<_putwchar_r>> and <<_putwchar_unlocked_r>> are |
|
|
86 |
reentrant versions of the above. The extra argument <[reent]> is a pointer |
|
|
87 |
to a reentrancy structure. |
|
|
88 |
|
|
|
89 |
RETURNS |
|
|
90 |
If successful, <> returns its argument <[wc]>. If an error |
|
|
91 |
intervenes, the result is <>. You can use `<>' to |
|
|
92 |
query for errors. |
|
|
93 |
|
|
|
94 |
PORTABILITY |
|
|
95 |
<> is required by C99. |
|
|
96 |
|
|
|
97 |
<> is a GNU extension. |
