ATOI(3)                  BSD Library Functions Manual                  ATOI(3)

     atoi, atoi_l -- convert ASCII string to integer

     Standard C Library (libc, -lc)

     #include <stdlib.h>

     atoi(const char *str);

     #include <xlocale.h>

     atoi_l(const char *str, locale_t loc);

     The atoi() function converts the initial portion of the string pointed to by str to int representation.

     It is equivalent to:

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

     While the atoi() function uses the current locale, the atoi_l() function may be passed a locale
     directly. See xlocale(3) for more information.

     The atoi() and atoi_l() functions are thread-safe and async-cancel-safe.

     The atoi() and atoi_l() functions have been deprecated by strtol() and strtol_l() and should not be
     used in new code.

     The function atoi() need not affect the value of errno on an error.

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

     The atoi() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1''), ISO/IEC 9899:1990 (``ISO C90''), and
     ISO/IEC 9899:1999 (``ISO C99'').
