Syntax
Copy
INT RtAtoi(
LPCSTR lpString
);Parameters
lpString
The source character string.
Return Value
If the function succeeds, it returns:
- An INT value produced by the conversion
If the function fails, it returns:
- Zero if the input cannot be converted
- INT_MAX if the converted value is too large for the return variable range
- INT_MIN if the converted value is too small for the return variable range
Remarks
RtAtoi is like atoi, but RtAtoi does not require the C runtime library and can work with any combination of run-time libraries.
This function supports decimal digits only and does not allow leading whitespace or signs.
