ATOL(3) 						   BSD Library Functions Manual 						   ATOL(3)

NAME

     atol, atoll, atol_l, atoll_l -- convert ASCII string to long or long long integer

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <stdlib.h>

     long
     atol(const char *str);

     long long
     atoll(const char *str);

     #include <xlocale.h>

     long
     atol_l(const char *str, locale_t loc);

     long long
     atoll_l(const char *str, locale_t loc);

DESCRIPTION

     The atol() function converts the initial portion of the string pointed to by str to long integer representation.

     It is equivalent to:

	   strtol(str, (char **)NULL, 10);

     The atoll() function converts the initial portion of the string pointed to by str to long long integer representation.

     It is equivalent to:

	   strtoll(str, (char **)NULL, 10);

     While the atol() and atoll() functions use the current locale, the atol_l() and atoll_l() functions may be passed locales directly. See
     xlocale(3) for more information.

ERRORS

     The functions atol() and atoll() need not affect the value of errno on an error.

SEE ALSO

     atof(3), atoi(3), strtod(3), strtol(3), strtoul(3), xlocale(3)

STANDARDS

     The atol() function conforms to ISO/IEC 9899:1990 (``ISO C90'').  The atoll() function conforms to ISO/IEC 9899:1999 (``ISO C99'').

IMPLEMENTATION NOTES

     The atol(), atoll(), atol_l(), and atoll_l() functions are thread-safe and async-cancel-safe.

     The FreeBSD implementations of the atol() and atoll() functions are thin wrappers around strtol() and stroll() respectively, so these func-
     tions will affect the value of errno in the same way that the strtol() and stroll() functions are able to.  This behavior of atol() and
     atoll() is not required by ISO/IEC 9899:1990 (``ISO C90'') or ISO/IEC 9899:1999 (``ISO C99''), but it is allowed by all of ISO/IEC 9899:1990
     (``ISO C90''), ISO/IEC 9899:1999 (``ISO C99'') and IEEE Std 1003.1-2001 (``POSIX.1'').

ERRORS

     The functions atol() and atoll() may affect the value of errno on an error.

SEE ALSO

STANDARDS

     The atol() function conforms to ISO/IEC 9899:1990 (``ISO C90'').  The atoll() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
