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);

IMPLEMENTATION NOTES

     The atoi() function is not thread-safe and also not async-cancel safe.

     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'').
