ATOI(3) OpenBSD Programmer's Manual ATOI(3)
NAME
atoi - convert ASCII string to integer
SYNOPSIS
#include <stdlib.h>
int
atoi(const char *nptr);
DESCRIPTION
The atoi() function converts the initial portion of the string pointed to
by nptr to integer representation.
It is equivalent to:
(int)strtol(nptr, (char **)NULL, 10);
CAVEATS
atoi does no overflow checking, handles unsigned numbers poorly, and han-
dles strings containing trailing extra characters (like ``123abc'') poor-
ly. Careful use of strtol(3) and strtoul(3) can alleviate these prob-
lems.
SEE ALSO
atof(3), atol(3), strtod(3), strtol(3), strtoul(3)
STANDARDS
The atoi() function conforms to ANSI X3.159-1989 (``ANSI C'').
