ATOL(3) BSD Library Functions Manual ATOL(3) NAME atol, atoll, atol_l, atoll_l -- convert ASCII string to long or long long integer LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <stdlib.h> long atol(const char *str); long long atoll(const char *str); #include <xlocale.h> long atol_l(const char *str, locale_t loc); long long atoll_l(const char *str, locale_t loc); DESCRIPTION The atol() function converts the initial portion of the string pointed to by str to long integer representation. It is equivalent to: strtol(str, (char **)NULL, 10); The atoll() function converts the initial portion of the string pointed to by str to long long integer representation. It is equivalent to: strtoll(str, (char **)NULL, 10); While the atol() and atoll() functions use the current locale, the atol_l() and atoll_l() functions may be passed locales directly. See xlocale(3) for more information. ERRORS The functions atol() and atoll() need not affect the value of errno on an error.
