!!DESCRIPTION |

26 |
|
| |
|
27 |
|
| |
|
28 |
__fputc()__ writes the character ''c'', cast to an |
| |
|
29 |
__unsigned char__, to ''stream''. |
| |
|
30 |
|
| |
|
31 |
|
| |
|
32 |
__fputs()__ writes the string ''s'' to ''stream'', |
| |
|
33 |
without its trailing __'0'__. |
| |
|
34 |
|
| |
|
35 |
|
| |
|
36 |
__putc()__ is equivalent to __fputc()__ except that it |
| |
|
37 |
may be implemented as a macro which evaluates ''stream'' |
| |
|
38 |
more than once. |
| |
|
39 |
|
| |
|
40 |
|
| |
|
41 |
__putchar(__''c''__);__ is equivalent to |
| |
|
42 |
__putc(__''c''__,__''stdout''__).__ |
| |
|
43 |
|
| |
|
44 |
|
| |
|
45 |
__puts()__ writes the string ''s'' and a trailing |
| |
|
46 |
newline to ''stdout''. |

Calls to the functions described here can be mixed with each |
| |
|
50 |
other and with calls to other output functions from the |
| |
|
51 |
__stdio__ library for the same output |
| |
|
52 |
stream. |
| |
|
53 |
!!RETURN VALUE |
| |
|
54 |
|
| |
|
55 |
|
| |
|
56 |
__fputc()__, __putc()__ and __putchar()__ return |
| |
|
57 |
the character written as an __unsigned char__ cast to an |
| |
|
58 |
__int__ or __EOF__ on error. |
| |
|
59 |
|
| |
|
60 |
|
| |
|
61 |
__puts()__ and __fputs()__ return a non - negative |
| |
|
62 |
number on success, or __EOF__ on error. |

| |
|

|
| |
|
70 |
It is not advisable to mix calls to output functions from |
| |
|
71 |
the __stdio__ library with low - level calls to |
| |
|
72 |
__write()__ for the file descriptor associated with the |
| |
|
73 |
same output stream; the results will be undefined and very |
| |
|
74 |
probably not what you want. |
