FUNCTION
<<atoi>>, <<atol>>---string to integer
INDEX
atoi
INDEX
atol
INDEX
_atoi_r
INDEX
_atol_r
ANSI_SYNOPSIS
#include <stdlib.h>
int atoi(const char *<[s]>);
long atol(const char *<[s]>);
int _atoi_r(struct _reent *<[ptr]>, const char *<[s]>);
long _atol_r(struct _reent *<[ptr]>, const char *<[s]>);
TRAD_SYNOPSIS
#include <stdlib.h>
int atoi(<[s]>)
char *<[s]>;
long atol(<[s]>)
char *<[s]>;
int _atoi_r(<[ptr]>, <[s]>)
struct _reent *<[ptr]>;
char *<[s]>;
long _atol_r(<[ptr]>, <[s]>)
struct _reent *<[ptr]>;
char *<[s]>;
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.
