ATOI(3)			   Linux Programmer's Manual		       ATOI(3)

NAME
       atoi, atol, atoll, atoq - convert a string to an integer

SYNOPSIS
       #include <stdlib.h>

       int atoi(const char *nptr);
       long atol(const char *nptr);
       long long atoll(const char *nptr);
       long long atoq(const char *nptr);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       atoll():
	   _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 ||
	   _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
	   or cc -std=c99

DESCRIPTION
       The atoi() function converts the initial portion of the string  pointed
       to by nptr to int.  The behavior is the same as

	   strtol(nptr, NULL, 10);

       except that atoi() does not detect errors.

       The atol() and atoll() functions behave the same as atoi(), except that
       they convert the initial portion of the string to their return type  of
       long or long long.  atoq() is an obsolete name for atoll().

RETURN VALUE
       The converted value.

CONFORMING TO
       SVr4,  POSIX.1-2001,  4.3BSD,  C99.   C89  and POSIX.1-1996 include the
       functions atoi() and atol() only.  atoq() is a GNU extension.

NOTES
       The nonstandard atoq() function is not present in libc 4.6.27 or	 glibc
       2, but is present in libc5 and libc 4.7 (though only as an inline func‐
       tion in <stdlib.h> until libc 5.4.44).  The atoll() function is present
       in glibc 2 since version 2.0.2, but not in libc4 or libc5.
