FUNCTION
   <<atoi>>, <<atol>>---string to integer

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.
