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 int representation.

     It is equivalent to:

	   (int)strtol(nptr, (char **)NULL, 10);

     The atoi() function has been deprecated by strtol() and should not be used in new code.

ERRORS
