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.
