84 | DESCRIPTION |
||
85 | < |
||
86 | stream identified by <[fp]>. |
||
87 | |||
88 | If the file was opened with append mode (or if the stream cannot |
||
89 | support positioning), then the new wide character goes at the end of the |
||
90 | file or stream. Otherwise, the new wide character is written at the |
||
91 | current value of the position indicator, and the position indicator |
||
92 | oadvances by one. |
||
93 | |||
94 | The < |
||
95 | may be implemented as a macro, and may evaluate its argument more than |
||
96 | once. There is no reason ever to use it. |
||
97 | |||
98 | The <<_fputwc_r>> and <<_putwc_r>> functions are simply reentrant versions |
||
99 | of < |
||
100 | argument: <[ptr]>. |
||
101 | |||
102 | RETURNS |
||
103 | If successful, < |
||
104 | If an error intervenes, the result is < |
||
105 | `< |
