| 14 | SYNOPSIS |
|---|
| 15 | #include <stdlib.h> |
|---|
| 16 | int atoi(const char *<[s]>); |
|---|
| 17 | long atol(const char *<[s]>); |
|---|
| 18 | int _atoi_r(struct _reent *<[ptr]>, const char *<[s]>); |
|---|
| 19 | long _atol_r(struct _reent *<[ptr]>, const char *<[s]>); |

| 20 | |
|---|
| 21 | DESCRIPTION |
|---|
| 22 | <<atoi>> converts the initial portion of a string to an <<int>>. |
|---|
| 23 | <<atol>> converts the initial portion of a string to a <<long>>. |
|---|
| 24 | |
|---|
| 25 | <<atoi(s)>> is implemented as <<(int)strtol(s, NULL, 10).>> |
|---|
| 26 | <<atol(s)>> is implemented as <<strtol(s, NULL, 10).>> |
|---|
| 27 | |
|---|
| 28 | <<_atoi_r>> and <<_atol_r>> are reentrant versions of <<atoi>> and |
|---|
| 29 | <<atol>> respectively, passing the reentrancy struct pointer. |
|---|
| 30 | |
|---|
| 31 | RETURNS |
|---|
| 32 | The functions return the converted value, if any. If no conversion was |
|---|
| 33 | made, <<0>> is returned. |
|---|
| 34 | |
|---|
| 35 | PORTABILITY |
|---|
| 36 | <<atoi>>, <<atol>> are ANSI. |
|---|
| 37 | |
|---|
| 38 | No supporting OS subroutines are required. |
