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 containing trailing extra characters (like ``123abc'')
     poorly.  Careful use of strtol(3) and strtoul(3) can alleviate these problems.
