atoi

OS/161 Reference Manual

Name

atoi - convert ascii to integer

Library

Standard C Library (libc, -lc)

Synopsis

#include <stdlib.h>

int
atoi(const char *string);

Description

string, which should be a textual representation of an integer, is converted to the machine representation of that integer. Leading whitespace, if any, is skipped. Conversion stops when a non-numeric character is found.

Return Values

atoi returns the number converted. If no digits at all were found, it returns 0. If too many digits are found (resulting in overflow) the behavior is formally undefined.
