SYNOPSIS

     #include <stdlib.h>

     long
     atol(const char *nptr);

     long long
     atoll(const char *nptr);

     #include <xlocale.h>

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

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

DESCRIPTION

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

     It is equivalent to:

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

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

     It is equivalent to:

           strtoll(nptr, (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.
