NetBSD 6.1.5 - man page for atoi (netbsd section 3)

ATOI(3) 			   BSD Library Functions Manual 			  ATOI(3)

NAME
     atoi -- convert ASCII string to integer

LIBRARY
     Standard C Library (libc, -lc)

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);

SEE ALSO
     atof(3), atol(3), strtod(3), strtol(3), strtoul(3)

STANDARDS
     The atoi() function conforms to ANSI X3.159-1989 (``ANSI C89'').

CAVEATS
     atoi does no overflow checking, handles unsigned numbers poorly, and handles strings con-
     taining trailing extra characters (like ``123abc'') poorly.  Careful use of strtol(3) and
     strtoul(3) can alleviate these problems.
