24 !!DESCRIPTION
25
26
27 The __atoi()__ function converts the initial portion of
28 the string pointed to by ''nptr'' to ''int''. The
29 behaviour is the same as
30
31
32 __strtol(nptr, (char **)NULL, 10);__
33
34
35 except that __atoi()__ does not detect
36 errors.
37

39 The __atol()__ and __atoll()__ functions behave the
40 same as __atoi()__, except that they convert the initial
41 portion of the string to their return type of ''long'' or
42 ''long long''. __atoq()__ is an obsolete name for
43 __atoll()__.

58 The non-standard __atoq()__ function is not present in
59 libc 4.6.27 or glibc 2, but is present in libc5 and libc 4.7
60 (though only as an inline function in
61 ____ until libc 5.4.44). The
62 __atoll()__ function is present in glibc 2 since version
63 2.0.2, but not in libc4 or libc5.
