A call to 47atoll(str) in this implementation is equivalent to 48strtoll(str, (char **)NULL, 10) including behavior on error. 49 50 <p>The alternate function <code>_atoll_r</code> is a reentrant version. The 51extra argument <var>reent</var> is a pointer to a reentrancy structure. 52 53 <p><br> 54<strong>Returns</strong><br> 55The converted value. 56 57 <p><br> 58<strong>Portability</strong><br> 59<code>atoll</code> is ISO 9899 (C99) and POSIX 1003.1-2001 compatable. 60 61 <p>No supporting OS subroutines are required. 62 63 <p><br> 64 65 </body></html> 66 67
