DESCRIPTION
|
|
<<atoi>> converts the initial portion of a string to an <<int>>.
|
|
<<atol>> converts the initial portion of a string to a <<long>>.
|
|
|
|
<<atoi(s)>> is implemented as <<(int)strtol(s, NULL, 10).>>
|
|
<<atol(s)>> is implemented as <<strtol(s, NULL, 10).>>
|
|
|
|
<<_atoi_r>> and <<_atol_r>> are reentrant versions of <<atoi>> and
|
|
<<atol>> respectively, passing the reentrancy struct pointer.
|
|
|
|
RETURNS
|
|
The functions return the converted value, if any. If no conversion was
|
|
made, <<0>> is returned.
|
|
|
|
PORTABILITY
|
|
<<atoi>>, <<atol>> are ANSI.
|
|
|
|
No supporting OS subroutines are required.
