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);

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

	      strtol(nptr, (char **)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
       SVID 3, POSIX.1, BSD 4.3, ISO/IEC 9899.	ISO/IEC 9899:1990 (C89) and POSIX.1 (1996 edition) include the functions atoi() and  atol()  only;
       C99 adds the function atoll().

NOTES
       The  non-standard  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
       function 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.
