NAME
atoi, atol, atoll - 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); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): atoll(): __ISOC99_SOURCE || || /* Glibc versions <= 2.19: */ _BSD_SOURCE || _SVID_SOURCE 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. RETURN VALUE
The converted value. ATTRIBUTES

POSIX.1-2001, POSIX.1-2008, C99, SVr4, 4.3BSD. C89 and POSIX.1-1996 include the functions atoi() and atol() only. NOTES
Linux libc provided atoq() as an obsolete name for atoll(); atoq() is not provided by glibc. SEE ALSO
