ATOI(3) BSD Library Functions Manual ATOI(3)
NAME
atoi, atoi_l -- convert ASCII string to integer
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
int
atoi(const char *str);
#include <xlocale.h>
int
atoi_l(const char *str, locale_t loc);
DESCRIPTION
The atoi() function converts the initial portion of the string pointed to by str to int representation.
It is equivalent to:
(int)strtol(str, (char **)NULL, 10);
While the atoi() function uses the current locale, the atoi_l() function may be passed a locale directly. See xlocale(3) for more informa-
tion.
IMPLEMENTATION NOTES
The atoi() and atoi_l() functions are thread-safe and async-cancel-safe.
The strtol() and strtol_l() functions are recommended instead of atoi() and atoi_l() functions, especially in new code.
ERRORS
The function atoi() need not affect the value of errno on an error.
SEE ALSO
atof(3), atol(3), strtod(3), strtol(3), strtoul(3), xlocale(3)
STANDARDS
The atoi() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1''), ISO/IEC 9899:1990 (``ISO C90''), and ISO/IEC 9899:1999 (``ISO C99'').
