DESCRIPTION |
|
|
39 |
<> converts the initial portion of a string to an <>. |
|
|
40 |
<> converts the initial portion of a string to a <>. |
|
|
41 |
|
|
|
42 |
<> is implemented as <<(int)strtol(s, NULL, 10).>> |
|
|
43 |
<> is implemented as <> |
|
|
44 |
|
|
|
45 |
<<_atoi_r>> and <<_atol_r>> are reentrant versions of <> and |
|
|
46 |
<> respectively, passing the reentrancy struct pointer. |
|
|
47 |
|
|
|
48 |
RETURNS |
|
|
49 |
The functions return the converted value, if any. If no conversion was |
|
|
50 |
made, <<0>> is returned. |
|
|
51 |
|
|
|
52 |
PORTABILITY |
|
|
53 |
<>, <> are ANSI. |
|
|
54 |
|
|
|
55 |
No supporting OS subroutines are required. |
