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 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
     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) 

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'').
