TRAD_SYNOPSIS |
|
|
35 |
#include |
|
|
36 |
int fputc(<[ch]>, <[fp]>) |
|
|
37 |
int <[ch]>; |
|
|

#include |
|
|
41 |
int _fputc_r(<[ptr]>, <[ch]>, <[fp]>) |
|
|
42 |
struct _reent *<[ptr]>; |
|
|

DESCRIPTION |
|
|
47 |
<> converts the argument <[ch]> from an <> to an |
|
|
48 |
<>, then writes it to the file or stream identified by |
|
|
49 |
<[fp]>. |
|
|
50 |
|
|
|
51 |
If the file was opened with append mode (or if the stream cannot |
|
|
52 |
support positioning), then the new character goes at the end of the |
|
|
53 |
file or stream. Otherwise, the new character is written at the |
|
|
54 |
current value of the position indicator, and the position indicator |
|
|
55 |
oadvances by one. |
|
|
56 |
|
|
|
57 |
For a macro version of this function, see <>. |
|
|
58 |
|
|
|
59 |
The <<_fputc_r>> function is simply a reentrant version of <> |
|
|
60 |
that takes an additional reentrant structure argument: <[ptr]>. |
|
|
61 |
|
|
|
62 |
RETURNS |
|
|
63 |
If successful, <> returns its argument <[ch]>. If an error |
|
|
64 |
intervenes, the result is <>. You can use `<)>>' to |
|
|
65 |
query for errors. |
|
|
66 |
|
|
|
67 |
PORTABILITY |
|
|
68 |
<> is required by ANSI C. |
|
|
69 |
|
|
|
70 |
Supporting OS subroutines required: <>, <>, <>, |
|
|
71 |
<>, <>, <>, <>. |
