ATOL(3)               DragonFly 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 *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, 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, NULL, 10);

     The _l-suffixed versions take an explicit locale argument, whereas the
     non-suffixed versions use the current global or per-thread locale.

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'').
