DESCRIPTION
|
|
sl@0
|
42 |
<<putc>> is a macro, defined in <<stdio.h>>. <<putc>>
|
|
sl@0
|
43 |
writes the argument <[ch]> to the file or stream identified by
|
|
sl@0
|
44 |
<[fp]>, after converting it from an <<int>> to an <<unsigned char>>.
|
|
sl@0
|
45 |
|
|
sl@0
|
46 |
If the file was opened with append mode (or if the stream cannot
|
|
sl@0
|
47 |
support positioning), then the new character goes at the end of the
|
|
sl@0
|
48 |
file or stream. Otherwise, the new character is written at the
|
|
sl@0
|
49 |
current value of the position indicator, and the position indicator
|
|
sl@0
|
50 |
advances by one.
|
|
sl@0
|
51 |
|
|
sl@0
|
52 |
For a subroutine version of this macro, see <<fputc>>.
|
|
sl@0
|
53 |
|
|
sl@0
|
54 |
RETURNS
|
|
sl@0
|
55 |
If successful, <<putc>> returns its argument <[ch]>. If an error
|
|
sl@0
|
56 |
intervenes, the result is <<EOF>>. You can use `<<ferror(<[fp]>)>>' to
|
|
sl@0
|
57 |
query for errors.
|
|
sl@0
|
58 |
|
|

|
59 |
PORTABILITY
|
|
sl@0
|
60 |
ANSI C requires <<putc>>; it suggests, but does not require, that
|
|
sl@0
|
61 |
<<putc>> be implemented as a macro. The standard explicitly permits
|
|
sl@0
|
62 |
macro implementations of <<putc>> to use the <[fp]> argument more than once;
|
|
sl@0
|
63 |
therefore, in a portable program, you should not use an expression
|
|
sl@0
|
64 |
with side effects as this argument.
|
|
sl@0
|
65 |
|
|
sl@0
|
66 |
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
sl@0
|
67 |
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
